Middle English (also in the sense 'quarreling'): from Old French, from Latin nausea 'seasickness' (see nausea).

  • nausea from Late Middle English:

    Nausea originally meant ‘seasickness’ and is based on the Greek word naus, ‘ship’ also the source of the English word nautical (mid 16th century). Noise (Middle English) also comes from nausea—as it developed through Latin and early French, nausea took on a series of meanings that went from ‘seasickness’ to ‘upset, malaise’, and ‘disturbance, uproar’, and so to ‘noise’, which was the word's spelling and meaning when it first appeared in medieval English.
