Acrid

Formed in English from Latin "acer" (stem "acri-," meaning "sharp, pungent, keen"), with an ending apparently modeled on "acid." The irregular "-id" is generally explained as influence from "acid" (Latin "acidus"). The result is a word for a smell or taste that is sharp to the point of harshness.

    Sharp and harsh, or bitterly unpleasant, in smell or taste.

    The word for the stinging sharpness of smoke, scorched things, or chemicals catching in the throat.

    Pungent is sharp but can be pleasant; acrid is sharp in a harsh, irritating, and usually unwelcome way.
