plausible vs. possible: What's the difference? Plausible means believable or having an appearance of truth. Possible means a thing that may or could happen or be true.

The main difference between “plausible” and “possible” is that “plausible” means you could make a reasonably valid case for something, while “possible” means something is capable of becoming true, though it’s not always reasonable. Both are adjectives, but they also have adverb and noun forms.

Plausible is used to describe something that appears to be true or reasonable based on surface-level information. It indicates believability. On the other hand, Possible simply denotes that something can happen, regardless of its credibility or likelihood.

Plausible suggests something is believable or likely to be true, while possible indicates something can happen or be done, without regard to its likelihood.

What’s the Difference between Possible and Plausible? Both words are similar, but they have different uses. Cambridge Dictionary defines possible as being able to be done or achieved, while plausible connotes being reasonable or able to be believed.
