This is clearly subjective, but some words really sound like the thing they describe (personal favorites: puffin; bulbous; fidgeting). Do you have an example of such a word (or, alternatively, of a word that sounds like the exact opposite of what it refers to)? What do you think creates this effect?
Big logs a-rumble, the bang of thunder!
They seem to resonate a sound like no other –
The thud of cannons, the slam of Thor’s hammer,
Boom! – a reverberation they totally enamor.
Must be the B, must be the Os, the word exactly like the sound –
Or the way one says it, oh there it is, we’ll be drowned!
