I've hit a bit of a stumbling block in the illimitable search for words that can be used to hammer nails, describe the upper lips of chickens, explain tautological inconsistencies, fill bowls with rice, and perform other day-to-day household chores faster and for less money. Specifically, can anyone suggest a good antonym for onomatopoeia?

One possibility is heterological, as used in Grelling's Paradox:

"If a homological adjective is one that is true of itself,
e.g., "polysyllabic", and a heterological adjective is one
which is not true of itself, e.g., "bisyllabic", then what
about "heterological?" Is it heterological or not?"

Another possibility is anamimesis, but I rejected this with its close relation anonomatopoeia because neither really addresses the roots of onomatopoeia; onomato (name) + poi (make). To be absent a name is not quite the point.

Perhaps moving the ana part in front of of the poi part -- onomatoanapoeia -- might be closer. I think the problem here is that onomatopoeia itself is rather a conceptual leap from its etymological roots. I expect if
there is an antonym, it will, like most antonyms, be constructed from different roots.

Finally, a couple of points to consider:

1) Should the antonym be for a word that doesn't sound like what it means, or a word that sounds like what it doesn't mean?

2) What if the word sounds like its antonym?

Thanks for any help!
