Other forms: cooling, cooler, cooled, coolest, cools

Cool is cold in the pleasant amount. The untouched side of the pillow, a stone floor under bare feet in August, the air that comes off a river in the evening.

Cool is a verb as well: you cool the soup by blowing on it, and a cake has to cool before you cut it. It is a noun in the cool of the morning, and in lose your cool, meaning lose your temper. Then there is the sense that has swallowed the others - cool as praise, for a jacket, a song, a person, a plan - and its small cousin, cool as a one-word yes: cool, see you at eight. Watch the unfriendly sense, because it hides inside polite sentences: a cool reception and a cool reply are not compliments, they mean distant. And a person who stays cool in a crisis is calm, not chilly.

Where it comes from

Cool comes straight down the Old English line, from col, which already meant cold and calm together, so the unflappable sense is a thousand years old rather than modern slang. Behind it stand Proto-Germanic *koluz and the Proto-Indo-European root *gel-, to be cold, to freeze. That same root fed Latin gelu, frost - and it is why German kuhl and Dutch koel look so familiar.

  1. Old English

    cōl

  2. Middle English

  3. English, today

    cool

Built from

  • *kalaną · Proto-Germanic — to be cold, to freeze

From Middle English cool, from Old English cōl. From Middle English cool, from Old English cōl (“cool, cold, tranquil, calm”), from Proto-West Germanic kōl(ī), from Proto-Germanic kōluz (“cool”), from kalaną (“to be cold, to freeze”), Proto-Indo-European gel- (“to be cold, to freeze”). 2
