Conversation

Have you read that article about climate change?

Yeah, I found it pretty interesting, but the author's arguments felt a bit tenuous.

I agree, some of the points seemed really weak and lacked evidence.

Exactly, it's hard to take those claims seriously when they're so tenuous.

Synonyms & Antonyms

Root Explanation

Tenuous → It is formed from "tenere" (meaning to hold) and the suffix "-ous" (meaning full of). The word describes something that is full of holding but in a weak or insubstantial way, hence fragile or weak.

Memory Tip

Think of something that is 'full of holding' but very weak — that's why tenuous means fragile or insubstantial.
