Quick Answer
The difference between “possible” and “possible” is that they are the exact same word. There is no difference in meaning, spelling, or usage. If you meant to ask about “possible” versus “probable” or “possible” versus “plausible,” those are distinct words with different meanings. “Possible” means something can exist, happen, or be done, while “probable” suggests something is likely to happen, and “plausible” means something appears reasonable or believable.
Have you ever paused while typing, wondering if you should use “possible” or “possible”? Here’s the honest truth: they’re the same word. You might be experiencing the strange phenomenon where a word suddenly looks wrong even though it’s spelled correctly what linguists call semantic satiation. Or perhaps you’re genuinely confused between “possible” and other similar-sounding or similar-meaning words like “probable,” “plausible,” or “potentially.”
What most people actually want to know when they search “possible or possible” is whether there’s a subtle distinction they’re missing. Maybe they’ve seen both spellings somewhere. Maybe they’re questioning their own memory. Whatever brought you here, you’re about to learn everything you need to know about “possible,” its correct usage, and how it compares to the words people actually confuse it with.
By the end of this guide, you’ll understand exactly when to use “possible,” when to reach for alternatives, and how to avoid the common traps that trip up even native English speakers.
What’s the Difference Between Possible and Possible?
Since we’re dealing with the exact same word, there is no difference. However, what people often mean when they ask this question is: what’s the difference between “possible” and “probable,” or “possible” and “plausible”? These are genuinely different words with distinct meanings that serve different purposes in communication.
Let’s break down what “possible” actually means and how it compares to words people commonly mix it up with.
| Word | Part of Speech | Meaning | Refers To | Typical Usage | Example |
|---|---|---|---|---|---|
| Possible | Adjective | Capable of existing, happening, or being done; within the realm of what can occur | Something that may or may not happen, but is not ruled out | Speculation, planning, problem-solving, discussing alternatives | “It’s possible we’ll finish the project early.” |
| Probable | Adjective | Likely to happen or be true; supported by evidence or reasoning | Something that has a strong chance of occurring | Predictions, forecasts, evidence-based statements | “Based on the weather forecast, rain is probable this afternoon.” |
| Plausible | Adjective | Seeming reasonable or probable; appearing worthy of belief | An argument, explanation, or story that sounds believable | Critical thinking, evaluating claims, storytelling | “His explanation for being late was perfectly plausible.” |
| Feasible | Adjective | Possible to do easily or conveniently; practical | A plan, project, or course of action that can be carried out | Project management, planning, resource evaluation | “Building the bridge within six months is not feasible with our current budget.” |
The key takeaway: “possible” simply means something isn’t impossible it could happen, even if the chances are slim. “Probable” takes it a step further and suggests it likely will happen. “Plausible” focuses on whether something sounds believable, not whether it’s actually true. “Feasible” adds the dimension of practicality and resources.
Is “Possible” a Grammar, Vocabulary, or Usage Issue?
Understanding “possible” is primarily a vocabulary and usage matter rather than a strict grammar rule.
Grammar classification: “Possible” functions as an adjective. It modifies nouns and pronouns to describe capability or potential. Its grammatical cousins include “impossible” (the opposite) and “possibility” (the noun form). In sentences, it typically appears before a noun (“a possible solution”) or after a linking verb (“It is possible”).
Vocabulary difference: The confusion people experience isn’t about spelling variations but about semantic precision. English has an unusually rich vocabulary for describing likelihood and capability. This linguistic wealth creates both opportunity and confusion opportunity to express nuanced meaning, confusion about which word fits best.
Usage difference: Native speakers often misuse “possible” when they mean “probable.” Consider this common workplace exchange: “Is it possible we’ll meet the deadline?” vs. “Is it probable we’ll meet the deadline?” The first asks whether it can be done at all. The second asks whether it’s likely given current circumstances. Smart speakers use these distinctions to communicate more precisely.
Interchangeability: These words are rarely interchangeable. “Possible” and “probable” occupy different points on the likelihood spectrum. “Plausible” occupies a different dimension entirely it’s about how things appear rather than how likely they are. A story can be plausible without being possible (a convincing science fiction tale) and possible without being plausible (a true event that sounds unbelievable).
Formal vs. informal English: “Possible” works comfortably in all registers. “Probable” appears more frequently in formal writing, scientific contexts, and professional forecasting. “Plausible” often appears in academic writing, legal contexts, and critical analysis. Understanding these usage patterns helps you select the right word for any situation.
Practical takeaway: Before you write “possible,” ask yourself: “Am I describing a possibility or a probability? Am I discussing likelihood or believability? Am I considering practicality or mere potential?”
Understanding “Possible”
Meaning
“Possible” comes from the Latin “possibilis,” meaning “that can be done.” It describes anything that can exist, happen, or be achieved even if the chance is only one in a million. Something possible is not ruled out by the laws of nature, logic, or practical constraints. It occupies the broadest category on the likelihood spectrum, encompassing everything from “technically possible but unlikely” to “absolutely certain.”

Subject: Regarding Project Timeline
Hello Alex,
It’s possible we’ll need an extra week for testing. I’m currently evaluating whether to request an extension or reassign resources to maintain our original schedule. Let’s discuss possible options during tomorrow’s meeting.
Best,
Priya
Daily Conversation Example
“Are you coming to Sarah’s party?”
“I’m not sure yet. It’s possible I’ll stop by, but I have that work deadline. Keep me posted if anything changes.”
One Learner Mistake
Incorrect: “Is it possible to raining tomorrow?”
Correct: “Is it possible that it will rain tomorrow?” or “Is it possible for it to rain tomorrow?”
The error happens when learners treat “possible” like a verb and follow it with a gerund incorrectly. Use “possible to” with the base verb or “possible that” with a full clause.
Mini Recap
“Possible” is your go-to word for anything that could happen, exist, or be done. It’s broad, flexible, and essential for discussing options, planning, and speculation.
Understanding “Probable”
Meaning
“Probable” means likely to happen or be true based on evidence, reasoning, or experience. It sits firmly on the “high likelihood” end of the spectrum. When you say something is probable, you’re suggesting there’s more than just a chance you’re saying it’s the likely outcome. Weather forecasts, economic predictions, and scientific conclusions often rely on this word to communicate confidence without absolute certainty.

Workplace Example
“The quarterly review indicates that budget cuts are probable unless we improve sales performance. While nothing is certain, we should prepare for this eventuality and develop contingency plans.”
Academic Example
“Given the correlation between study hours and exam scores, it is probable that students who engage in regular, spaced practice will outperform those who cram the night before.”
Technology Example
“Based on user behavior patterns, a system upgrade failure is probable during peak usage hours. Schedule maintenance for low-traffic periods to minimize disruption.”
Email Example
Subject: Q4 Projections
Dear Team,
After reviewing our current progress, it’s probable we’ll exceed our quarterly targets by 8-10%. This is promising news, though we should maintain our current pace rather than reducing effort. I’ll share more detailed projections after Friday’s data update.

Marcus
Daily Conversation Example
“Do you think they’ll get married?”
“I’d say it’s probable. They’ve been together for five years, just bought a house, and both talk about the future like they’re in it together. I’d be surprised if they didn’t tie the knot.”
One Learner Mistake
Incorrect: “It’s probable to rain this afternoon.”
Correct: “It’s probable that it will rain this afternoon.” or “Rain is probable this afternoon.”
Like “possible,” “probable” cannot be followed by “to” + infinitive. Use “that” + clause or use “probable” as a predicate adjective.
Mini Recap
“Probable” is your word for describing likely outcomes. Use it when you have reason to believe something will happen, not just when you’re speculating about possibilities. It shows you’ve considered the evidence.
What’s the Difference Between Possible, Probable, and Plausible?
These three words represent distinct concepts that learners often confuse. Here’s a quick breakdown:
Possible = Not impossible. The broadest category. If the laws of physics allow it, if logic permits it, if it’s within the realm of what could happen it’s possible. The chance might be 1% or 99% (or any number in between). “Possible” is about potential, not likelihood.
Probable = Likely. Narrower than possible. Something that’s probable has evidence supporting it. There’s reason to believe it will happen. If the chance is above 50%, “probable” is your word. It’s about likelihood and reasonable expectation.
Plausible = Believable. This operates on a different dimension. A plausible explanation sounds convincing and reasonable. It might be true, but plausibility focuses on how things appear rather than how likely they are. A alibi can be plausible but false. A theory can be plausible but unproven.
Consider this sentence: “It’s possible they’re related, probable they’re siblings, and their explanation for meeting is plausible but unverified.”
Practical application: When you’re discussing possibilities, use “possible” for anything that could happen. Use “probable” when you want to indicate likelihood based on evidence. Use “plausible” when discussing whether something seems reasonable or believable.
Understanding “Plausible”
Meaning
“Plausible” describes something that seems reasonable, believable, or worthy of acceptance. It’s about appearance and believability rather than actual truth or likelihood. A plausible argument sounds convincing even if it’s false. A plausible suspect appears to have a motive. This word is crucial in critical thinking because it reminds us that what seems reasonable isn’t always correct.

Typical Sentence Patterns
- It is plausible + that clause: “It’s plausible that the company’s success stems from its innovative culture.”
- Noun + is plausible: “His alibi is plausible but unverified.”
- More/less plausible: “Some conspiracy theories are more plausible than others.”
- Plausible + noun: “She offered a plausible explanation for the missing funds.”
Workplace Example
“While her excuse for being late sounds plausible, we should verify her timeline before accepting it as fact. Sometimes the most reasonable explanations are actually the least accurate.”
Academic Example
“The researcher proposed several plausible mechanisms for the observed effect, though she emphasized that plausibility doesn’t replace empirical verification.”
Technology Example
“Given the system logs, it’s plausible that user error caused the data loss, but we haven’t ruled out a security vulnerability.”

Dear Mr. Chang,
Your explanation for the delivery delay is plausible, though I would appreciate additional documentation supporting your timeline. Please send the relevant shipping records when you have a moment.
Sincerely,
Donna Reeves
Daily Conversation Example
“Did you believe her story about why she missed the meeting?”
“It was plausible, but something felt off. She had all the right details, but she avoided eye contact the whole time.”
One Learner Mistake
Incorrect: “The weather forecast is plausible for rain tomorrow.”
Correct: “The weather forecast’s prediction of rain tomorrow is plausible.”
“Plausible” describes beliefs, explanations, and arguments not events themselves. A prediction can be plausible, but a weather event itself cannot be plausible.
Mini Recap
“Plausible” focuses on believability. Use it when you’re evaluating explanations, arguments, or stories based on how convincing they seem, regardless of whether they’re actually true.
When Not to Use Each Word
Avoid Using “Possible” When You Mean “Probable”
Why it happens: People often use “possible” as a catch-all for any kind of chance, from minuscule to almost certain. This oversimplification creates ambiguity.
Which word is correct: Use “probable” when you want to communicate that something is likely, not merely possible.
How to remember: Think of probability as a percentage. Under 50%? Use “possible.” Over 50%? Use “probable.” If you’re not sure, but you have evidence suggesting likelihood, “probable” is more precise.
Example: “It’s possible the market will crash” (could happen, but no strong evidence) vs. “It’s probable the market will crash” (you’ve seen indicators suggesting it will).
Avoid Using “Possible” When You Mean “Feasible”
Why it happens: People equate possibility with practicality, but they’re different concepts.
Which word is correct: Use “feasible” when discussing whether something can be done with available resources, time, and skills.
How to remember: “Possible” asks, “Can it happen?” “Feasible” asks, “Can we do it?”
Example: “It’s possible to build a spaceship to Mars” vs. “It’s not feasible to build a spaceship to Mars with current funding and technology.
Avoid Using “Possible” When You Mean “Plausible”
Why it happens: The conflation of possibility with believability creates this common error.
Which word is correct: Use “plausible” when you’re discussing whether something sounds reasonable or convincing.
How to remember: “Possible” deals with reality; “plausible” deals with appearance. Something can be plausible but impossible, and possible but implausible.
Example: “It’s possible time travel exists” vs. “It’s plausible that time travel exists” (which suggests there’s a believable argument for it).
Avoid Using “Probable” When You Mean “Possible”
Why it happens: Sometimes people overstate what they can predict.
Which word is correct: Use “possible” when you’re acknowledging that something could happen but lack strong evidence that it will.
How to remember: Don’t use “probable” unless you have evidence. If you’re just speculating, stick with “possible.”
Example: “It’s probable she’ll win” (you’ve seen her in competition) vs. “It’s possible she’ll win” (anyone could win; you’re not making predictions).
Avoid Using “Probable” When You Mean “Plausible”
Why it happens: Confusing likelihood with believability creates this error.
Which word is correct: Use “plausible” for believability; use “probable” for likelihood based on evidence.
How to remember: Probability requires evidence; plausibility requires coherence and reasonableness.
Example: “Her explanation is plausible” (it sounds convincing) vs. “Her explanation is probable” (there’s evidence it’s true).
Avoid Using “Plausible” When You Mean “Possible” or “Probable”
Why it happens: People sometimes use “plausible” when they mean “possible” or “probable” because they confuse appearing reasonable with actual likelihood.
Which word is correct: Distinguish between appearance and reality. If you’re talking about what could happen, use “possible.” If you’re discussing what likely will happen, use “probable.” Reserve “plausible” for how things appear.
How to remember: The “plau-” in “plausible” connects to “applause” people applaud what appears good, not what’s actually true.
Example: “It’s plausible the company is struggling” (sounds reasonable) vs. “It’s possible the company is struggling” (could be true, but no evidence) vs. “It’s probable the company is struggling” (you’ve seen the numbers).
Common Mistakes Table
| Correct Sentence | Incorrect Sentence | Explanation |
|---|---|---|
| “It’s possible that we’ll finish by Friday.” | “It’s possible to finish by Friday?” | Use “possible to” with a verb (“It’s possible to finish”) or “possible that” with a clause. Don’t combine both. |
| “Rain is probable this afternoon.” | “Rain is possible this afternoon.” | The first communicates likelihood based on the forecast; the second only says rain could happen. Use the right word for the meaning you intend. |
| “Her explanation seems plausible.” | “Her explanation seems possible.” | “Possible” describes whether the explanation could be true; “plausible” describes whether it sounds believable. They’re not interchangeable. |
| “Is it possible to learn two languages at once?” | “Is it possible learning two languages at once?” | Use the infinitive after “possible.” The gerund (“learning”) is incorrect in this construction. |
| “The proposed timeline is not feasible.” | “The proposed timeline is not possible.” | “Possible” suggests it’s not physically impossible; “feasible” suggests it’s not practical. Different meanings for different contexts. |
| “He offered a plausible excuse.” | “He offered a possible excuse.” | The first suggests the excuse was believable; the second suggests he had an excuse. Different meanings entirely. |
| “It’s probable they’ll accept the offer.” | “It’s possible they’ll accept the offer.” | The first expresses confidence based on evidence; the second is just speculation. Choose based on your evidence. |
Quick Decision Guide
| Situation | Use This Word | Example |
|---|---|---|
| You’re describing anything that could happen, even if unlikely | Possible | “It’s possible aliens exist somewhere in the universe.” |
| You’re saying something will likely happen based on evidence | Probable | “Based on current trends, a recession is probable.” |
| You’re describing an argument, explanation, or story that sounds believable | Plausible | “His story about the traffic is plausible.” |
| You’re discussing whether something can be practically accomplished | Feasible | “Completing the project in two months is feasible with our resources.” |
| You’re talking about future events with any degree of uncertainty | Possible | “A ceasefire is possible if both sides negotiate.” |
| You’re making predictions and want to show you’ve considered the evidence | Probable | “The defendant is probably guilty based on the evidence.” |
| You’re evaluating whether an idea or theory seems reasonable | Plausible | “Her hypothesis is plausible, but it needs testing.” |
| You’re discussing resources, costs, or practical constraints | Feasible | “The solution is technically possible but not economically feasible.” |

Incorrect: “The model can produce plausible responses to any prompt, making its responses possible.”
Correct: “The model can produce plausible responses that sound believable, though their factual accuracy is not always probable. It’s possible the model will generate misinformation, which is why human verification remains essential.”
Why it works: The correct version demonstrates how these words work together to describe different aspects of AI performance.
Daily Conversation
Scenario: Friends discussing weekend plans.
Incorrect: “The beach is possible on Saturday.”
Correct: “The beach is possible on Saturday if the weather holds, but rain is probable based on the forecast. Maybe we should consider an indoor alternative.”

Modern Technology Usage
The distinction between “possible,” “probable,” and “plausible” has become increasingly important in the age of artificial intelligence.
Artificial Intelligence: When discussing AI capabilities, “possible” describes what AI systems can theoretically do. “Probable” describes what they typically produce based on training data. “Plausible” describes outputs that sound believable even when incorrect. This distinction is crucial: ChatGPT can produce plausible but factually incorrect responses (plausible, not always possible or probable).
Virtual Assistants: Voice assistants like Siri and Alexa function by determining what’s possible (what they can do), what’s probable (what you likely want), and what’s plausible (what they can understand and respond to). Understanding these distinctions helps users set reasonable expectations.
Software: When software developers discuss feature implementation, “possible” means the feature can be built, “feasible” means it can be built with available resources, and “probable” means it’s likely to work as intended.
Business Tools: Analytics platforms use “possible” to discuss hypothetical scenarios, “probable” to describe predicted outcomes based on data, and “plausible” to suggest reasonable interpretations of data.
Word Origins
“Possible” entered English in the 14th century from Latin “possibilis,” meaning “that can be done,” derived from “posse” meaning “to be able.” The word’s core meaning has remained remarkably stable over centuries.
“Probable” comes from Latin “probabilis,” meaning “worthy of approval” or “credible,” from “probare” meaning “to test, approve, or prove.” The meaning shifted from “worth believing” to “likely to be true” over time.
“Plausible” originates from Latin “plausibilis,” meaning “deserving applause,” from “plaudere” meaning “to applaud.” This fascinating origin reveals the word’s core meaning: something that deserves approval or appears worthy of belief.
These origins reveal how each word developed its current meaning. “Possible” focuses on ability and potential. “Probable” focuses on credibility and proof. “Plausible” focuses on appearance and approval.
Expert Insight
The most common mistake English learners make isn’t confusing these words it’s avoiding them altogether. Many non-native speakers stick with “possible” for every situation because it feels safe and familiar. This creates a gap between what they actually mean and what they communicate.
Think of these words as tools in your linguistic toolkit. “Possible” is your general-purpose screwdriver it handles most situations. “Probable” is your torque wrench it adds precision when you need it. “Plausible” is your level it helps you assess whether something is straight and reasonable. “Feasible” is your power drill it gets specific work done when you’re discussing practicality.
The real insight isn’t memorizing definitions; it’s recognizing that language gives you the power to be precise. When you say “possible,” you’re leaving your meaning open to interpretation. When you say “probable,” you’re telling your reader or listener, “I’ve thought about this, and here’s my informed opinion.” When you say “plausible,” you’re saying, “This sounds right, but I’m not vouching for truth.” Each choice communicates something different about your relationship to the information.
For professional communication, this precision builds trust. People who use these words correctly demonstrate they think carefully about what they’re saying. They’re not just filling space with words they’re making considered choices about the meaning they want to convey.
Error Prevention Checklist
- ✅ Always use “possible” when you’re describing anything that could happen, even if the chance is small, or when you’re discussing capabilities and theoretical potential.
- ✅ Always use “probable” when you have evidence or reasoning that suggests something is likely to happen or be true, or when you’re making predictions based on available information.
- ✅ Never confuse them if you’re discussing whether something sounds believable (“plausible”) versus whether it could actually happen (“possible”) or whether it’s likely given the evidence (“probable”).
- ✅ Quick memory tip: Draw a line from left to right on a likelihood scale. “Possible” covers everything from 1% to 100%. “Probable” specifically covers 51% to 100%. “Plausible” isn’t on the likelihood scale at all it’s on the believability scale. “Feasible” is on the practicality scale. Know which scale you’re using.
Related Grammar Confusions
- Affect vs. Effect – Two words with different parts of speech and meanings that even native speakers mix up. Worth learning because they appear constantly in professional writing.
- Imply vs. Infer – One describes what a speaker does; the other describes what a listener does. Understanding the difference improves both speaking and listening skills.
- Elicit vs. Illicit – One means to draw out; the other means illegal or forbidden. Simple to learn, easy to confuse in writing.
- Discreet vs. Discrete – One means careful or unobtrusive; the other means separate or distinct. Identical pronunciation makes them tricky for non-native speakers.
- Compliment vs. Complement – One involves praise; the other involves completion. Confusing these changes meaning entirely.
- Than vs. Then – One compares; the other indicates time or sequence. A basic distinction that many adults still struggle with.
- Your vs. You’re – One shows possession; the other is a contraction. The apostrophe makes all the difference.
- There vs. Their vs. They’re – Three distinct meanings with distinct functions. Master this set for more polished writing.
- To vs. Too vs. Two – Preposition vs. adverb vs. number. These homophones create beginner confusion that often persists without targeted practice.
- Whose vs. Who’s – Possessive vs. contraction. Understanding this distinction shows attention to detail in writing.
FAQs
Are “possible” and “possibly” the same?
No. Possible is an adjective, while possibly is an adverb. Use possible to describe something that can happen or exist, such as “a possible solution.” Use possibly to modify a verb or statement, such as “She could possibly arrive later.”
When should I use “possible” instead of “probable”?
Use possible when something can happen, without saying that it is likely. Use probable when available evidence or circumstances suggest that something is likely to happen. For example, “Rain is possible” only indicates a chance, while “Rain is probable” suggests a stronger likelihood.
What makes something plausible rather than possible?
Possible means that something can happen or exist. Plausible means that something seems believable or reasonable. An idea can be possible without being particularly convincing, while a plausible explanation sounds credible even if it has not been proven.
Can something be both possible and probable?
Yes. An event can be possible because it can happen and probable because it is likely to happen. The two words emphasize different levels of certainty. Something that is probable is generally possible, but something that is possible is not necessarily probable.
What’s an easy way to remember the difference?
Think of the terms as different levels of likelihood:
Possible = it could happen.
Probable = it is likely to happen.
Plausible = it seems believable.
Feasible = it is practical or achievable.
This simple distinction can make the words easier to choose correctly.
How do I use “possible” in a sentence correctly?
Common structures include “It is possible to + verb” and “It is possible that + clause.” For example, “It is possible to finish today” and “It is possible that we will finish today.” Avoid constructions such as “It is possible finishing today.”
What’s the noun form of “possible”?
The noun form is possibility. For example, “There is a possibility of delays” or “We should consider every possibility.” The plural form is possibilities.
Is “possible” ever used as a noun?
Rarely. Possible is normally an adjective, but specialized contexts may use possibles to refer to possible choices, outcomes, or alternatives. This noun usage is uncommon in everyday English.
Is “potentially” the same as “possibly”?
Not quite. Possibly focuses on whether something might happen, while potentially emphasizes the capacity or possibility of something developing into a particular outcome. For example, “She could possibly win” focuses on chance, while “She is potentially the strongest candidate” focuses on her potential.
Can I use “possible” in academic writing?
Yes. Possible is completely appropriate in academic writing and is widely used in scholarly discussions. Expressions such as theoretically possible, logically possible, and empirically possible can add useful precision when discussing different types of potential outcomes.
Conclusion
The distinction between “possible,” “probable,” and “plausible” is one of English’s most practical vocabulary distinctions. While “possible” is the broad umbrella term for anything that can happen, “probable” narrows the focus to likely outcomes, and “plausible” shifts the discussion to what sounds reasonable.
Understanding these differences transforms your communication from vague to precise. When you say something is possible, you’re acknowledging potential. When you say something is probable, you’re expressing confidence based on evidence. When you say something is plausible, you’re evaluating credibility. These distinctions matter in professional writing, academic work, and everyday conversation.
The rule you need to remember: if you’re not sure, ask yourself whether you’re discussing potential, likelihood, believability, or practicality. The answer will guide you to the right word. And if you’re still not sure, “possible” is always a safe fallback just remember that more precise options exist when you need them.
