Is "brittle" an onomatopoeia?

The double-t is probably meant to at least approach the sound of something brittle breaking.

There's a poem called "Anthem for Doomed Youth" in which one line has these words: "rifles' rapid rattle." These words are intended to imitate the sound of bullets hitting things.

ok thank you!

The word brittle sounds something brittle being crushed between your fingers.

Prove:
/Bri/- The initial break.
/tt/- The secondary breaks.
/le/- The final breaks that produce the sand like particles.

No, the word "brittle" is not an onomatopoeia. Onomatopoeia refers to words that imitate or represent sounds. For example, words like "buzz," "crash," or "hiss" are considered onomatopoeic because they sound similar to the noises they describe. In contrast, "brittle" is simply an adjective that describes something that is easily broken or fragmented. To determine if a word is an onomatopoeia, you can try to see if it resembles the sound it is associated with. Unfortunately, "brittle" does not resemble any sound, so it does not fall into the category of onomatopoeia.
