In Word/Play today we talk about
nauseate (v)
nauseous (adj)
nausea (n)
ad nauseam (a Latin phrase meaning something like 'until sick')
These all have to do with becoming sick. Usually it has to do with your stomach feeling bad and maybe you feel like throwing up. Oddly enough, the root word ~ nau ~ is the same root word for navy and naval. And, they all meant seasick although they have never been used for seasickness.
In your Trilingual Lesson we have very familiar words:
Nausea 吐き気
Nauseous 吐き気を催させる
Nauseate 吐き気を催す
Ad Nauseam うんざり
