AD NAUSEUM

RIGHT:

AD NAUSEAM

Seeing how often ad nauseam is misspelled makes some people want to throw up. English writers also often mistakenly half-translate the phrase as ad nausea.

This Latin phrase comes from a term in logic, the argumentum ad nauseam, in which debaters wear out the opposition by just repeating arguments until they get sick of the whole thing and give in.
