Example

The story he told was so strange that it seemed implausible to everyone.

Conversation

Did you hear that story about the man who claimed he could fly?

Yeah, it sounds completely implausible to me.

I know, right? It's hard to believe anyone would take that seriously.

Exactly! Some things are just too far-fetched to be true.

Synonyms & Antonyms

Root Explanation

Implausible → It is formed from "in-" (meaning not) and "plausibilis" (from Latin, meaning worthy of applause or approval). The word "implausible" means not worthy of belief or unlikely to be true.

Memory Tip

Think of 'not' ('in-') being combined with something that is 'worthy of approval' ('plausibilis') — this helps you remember that implausible means something that is not believable.
