chill

chill: [14] Old English had a noun cele or ciele ‘cold’ (from the same Germanic base as cold) which developed into Middle English chile ‘cold, frost’. Gaps in the record, however, cast doubt on whether this was the direct ancestor of the modern English noun, which may more plausibly be derived from the verb chill. This has been tentatively traced back to a hypothetical Old English verb *cieldan (also from the same Germanic base as cold), whose later form child may have been misinterpreted as a past participle, giving the new base form chill. Chilblain [16] is a compound formed from chill and blain ‘blister’, which comes from Old English blegen.

chill (n.)

Old English ciele, cele "cold, coolness, chill, frost," from Proto-Germanic *kal- "to be cold," from PIE root *gel- "cold" (see cold). According to OED, the word seems to have been obsolete after c. 1400 (displaced by cold) and the modern use is a back-formation since c. 1600 from the verb.

chill (v.)

late 14c., intransitive, "to feel cold, grow cold;" c. 1400, transitive, "to make cold," from chill (n.). Related: Chilled; chilling; chillingly. Figurative use from late 14c. Meaning "hang out" first recorded 1985; from earlier chill out "relax" (1979).
