"Sound words".Remus said:onomatopoeia. Is there a better word that means what this word means?
Boom, crash, smash, zip, swoosh, woof, pow.
Sound words.
Onomatopoeia means "Name(s) I make" from two Greek words.
But let's face it, you can make a name for anything and we simply call that "language".
They're sound words.
