What Is The Definition Of Plausible? | Meaning And Use

Maybe you have heard a story that sounded neat on the surface, yet you still felt a little unsure about it. In that moment you were judging whether the story felt plausible. English speakers use this word every day in news reports, essays, and casual talk, so a clear sense of its meaning helps you read and write with more precision. Learners ask what is the definition of plausible when they meet word in class.

What Is The Definition Of Plausible? In Everyday Language

In simple terms, plausible describes something that appears true enough that a reasonable person could accept it. A plausible explanation, excuse, or story fits the known facts, does not clash with common experience, and gives people a solid reason to nod and say, “That could be right.”

In many dictionaries, the main sense of plausible sits close to phrases such as “appearing worthy of belief” or “seeming likely to be true.” Some sources add a slightly negative tone for cases where something only sounds good on the surface. In regular use, though, people mostly rely on plausible as a neutral word for ideas that feel believable.

To see how this works, compare plausible with a few close neighbours in English.

Word	Core Idea	Sample Sentence
Plausible	Seems believable, fits the facts	That is a plausible explanation for the delay.
Possible	Could happen, no claim about how likely	Rain is possible, so pack a light jacket.
Probable	More likely than not to be true or to happen	Based on the data, a price rise is probable.
Credible	Trustworthy source or claim	The reporter gave a credible account of events.
Believable	Easy to accept as true	Her acting made the character completely believable.
Realistic	Matches how things work in real life	The plan sounds realistic for a small team.
Tenable	Can be defended with good arguments	Once new evidence appeared, his claim was no longer tenable.
Implausible	Hard to believe, strains common sense	The story became implausible once he changed the timeline.

Each of these nearby words shows a different shade of belief. Plausible leans toward everyday judgment: does this story, plan, or guess sound like it fits the world as you know it?

Definition Of Plausible In Formal Dictionaries

Major English dictionaries describe plausible in ways that overlap. One widely used American dictionary defines it as “seemingly fair, reasonable, or valuable” and also as “appearing worthy of belief.” Another major learner’s dictionary describes a plausible explanation as “reasonable and likely to be true.” These short lines all point to the same core idea: something counts as plausible when it lines up with both facts and common experience, even if proof is not complete yet.

If you look at detailed entries, you may also see an older sense of plausible that once meant “worthy of applause” or “pleasing to hear.” Modern speakers rarely use the word this way. That older sense survives mainly in history notes and helps show how the modern meaning grew from praise for a smooth or persuasive speaker toward the current focus on believable claims.

Some dictionary entries also record a slightly negative shade, where a plausible person sounds smooth and persuasive in a way that may hide weak facts. The core idea of believability stays the same, but the tone changes. Context around the sentence tells you whether the writer simply means “believable” or hints at “too good to be true.”

For precise reference, you can check detailed usage notes in sources such as the Merriam-Webster dictionary entry for plausible or the learner-focused definition in the Cambridge Dictionary. These resources list common senses, example sentences, and typical collocations.

How To Use Plausible In Sentences

Writers and speakers rarely say the word alone. Instead, plausible usually pairs with a noun such as “explanation,” “story,” “reason,” or “scenario.” These pairings help listeners see what kind of claim feels believable.

Plausible With Explanations And Reasons

One of the most common patterns is “plausible explanation.” Here are a few natural sentence shapes:

• The committee asked for a plausible explanation of the missing funds.
• Weather data offered a plausible reason for the low turnout.
• She gave a plausible excuse for arriving late to the meeting.

In each sentence, the person speaking does not claim full proof. Instead, the explanation matches known facts well enough that people can accept it unless stronger evidence appears.

Plausible With Stories And Scenarios

Plausible also works well with “story,” “scenario,” or “outcome.” These phrases help readers picture how events might play out:

• The novel offers a plausible long-term scenario for the city.
• Analysts described several plausible outcomes for the election.
• The film keeps the plot just plausible enough to feel grounded.

Notice how these sentences place plausible between wild fantasy and dull certainty. The events might not happen exactly as told, yet they fit what we know about people, systems, and limits.

Talking About People As Plausible

Sometimes speakers call a person “a plausible candidate” or “a plausible rival.” Here, the word still points to believability. A plausible candidate for a job or an office matches the known requirements and has a realistic chance of success.

Writers also use plausible in a slightly wary way. A “plausible salesman” might sound smooth and charming while hiding major details. In that tone, plausible points to appearances more than solid proof. The person looks honest, yet the speaker is not fully convinced.

Definition Of Plausible In Different Fields

So far the discussion has centered on everyday English. In some fields, though, the word picks up slightly sharper meanings. These uses still connect back to the main sense of “appearing worthy of belief,” but the context tightens the standard.

Scientific And Academic Writing

In research papers, writers often describe a model, theory, or hypothesis as plausible when it fits current evidence and accepted background knowledge. A plausible hypothesis explains the data well, does not clash with existing results, and yields testable predictions. It may later turn out wrong, yet at the time it stands as a serious candidate.

Law, Debate, And Everyday Argument

In law and public debate, speakers often weigh “plausible arguments” on both sides. A lawyer might say that the evidence backs a plausible defence. Commentators might talk about a plausible reading of a policy or a contract.

Here, plausible reflects both the internal logic of the claim and how well it fits the evidence on record. Judges, juries, and audiences all rely on this sense when they ask whether a story of events hangs together.

Plausibility As A Scale

Many writers treat plausibility as a sliding scale rather than a simple yes or no label. An idea can be barely plausible, quite plausible, or highly plausible, depending on how strong the reasons feel. In casual speech, people might say a plan “sounds plausible” to show that it clears a basic bar of believability, even if doubts remain.

Native speakers often shift among possible, plausible, and probable without much thought. For learners, though, drawing a rough line between them can sharpen both reading and writing.

Plausible, Possible, Probable: A Scale Of Believability

The next table shows one simple way to picture the relationship among these terms. It is not a strict rule, yet it matches how many speakers use them in practice.

Term	Rough Position On The Scale	Typical Use
Possible	Anything that could happen without breaking facts or logic	“It is possible that the train will be late.”
Plausible	Fits the facts and feels believable to a reasonable person	“Given the forecast, delays seem plausible.”
Probable	More likely than not based on strong reasons or data	“Heavy rain makes delays probable on that line.”
Certain	No realistic doubt remains	“The line is closed, so delays are certain.”

This scale does not replace careful numbers, yet it captures how many speakers hear the words. Possible covers the widest range and says little about likelihood. Probable signals strong expectation. Plausible sits in the middle, pointing to ideas that deserve serious thought but still leave room for doubt.

Common Mistakes With Plausible

Because plausible overlaps with several other adjectives, learners sometimes slide into small errors. Spotting these issues makes it easier to choose the right word.

Confusing Plausible With Possible

These two can trade places in casual speech, yet they do not always work in the same slot. Possible only states that something could happen. Plausible suggests a real basis for belief. Saying that a rare event is plausible implies more backing than the facts may warrant.

When you simply want to leave the door open for an unlikely event, possible fits better. When you want to say that a claim deserves serious consideration based on the evidence, plausible has more force.

Overusing Plausible As Praise

Because plausible sits close to credible and believable, some writers treat it as strong praise. In reality the word stays more cautious. Calling an idea plausible does not crown it as the winner. It simply marks it as worth testing, debating, or watching.

When you want to give stronger approval, words such as “convincing,” “solid,” or “well founded” may fit better, depending on the tone you want.

Forgetting The Slightly Negative Tone

In some settings, plausible carries a faint warning. A “plausible liar” or a “plausible cover story” may sound smooth while hiding gaps. In crime novels and thrillers, detectives often cut through stories that seem plausible at first and later fall apart under close reading.

This tone depends on the nouns and verbs around the word. When you attach plausible to “scheme,” “excuse,” or “cover story,” readers may expect trouble. When you attach it to “model,” “approach,” or “reading,” the tone stays neutral or mildly positive.

Pronunciation, Spelling, And Word Family

Plausible usually appears in careful writing, so spelling matters. The word shares its root with “applaud” and “applause,” which can help fix the pattern “plau-” in your mind.

Standard dictionaries give the main pronunciation as /ˈplɔː.zə.bəl/ in British English and /ˈplɑː.zə.bəl/ in American English. Both start with a “plaw” sound, followed by a soft “zuh,” then “buhl.” Saying it out loud a few times can build a natural rhythm.

The most common related forms are plausibility, meaning the quality of being plausible, and plausibly, the adverb. Plausibility often appears in academic writing when authors rate how strongly the evidence backs each hypothesis or scenario.

Quick Reference Checklist For Using Plausible

To finish, here is a short checklist that ties together the main points about what is the definition of plausible and how to use it well:

• Use plausible for claims, stories, and plans that seem believable and fit the known facts.
• Pair plausible with nouns such as explanation, reason, story, scenario, outcome, and candidate.
• Reserve possible for anything that could happen, and probable for outcomes that evidence strongly favors.
• Watch the tone around plausible; with words like excuse or cover story it can hint at smooth but shaky claims.
• Remember related forms such as plausibility and plausibly when you need nouns or adverbs in more formal writing.

Use plausible when a claim sounds believable, yet still leaves space for fresh evidence or doubt.
