What does chillily mean?
"Chillily" is an adverb formed from the adjective "chilly," meaning in a cold manner. Its dominant modern sense is figurative: it describes behaviour that is unfriendly, reserved, or marked by quiet disapproval — a host might greet an unexpected guest chillily, or a colleague might respond to criticism with a chillily polite reply. A secondary, more literary sense describes physical coldness, as when wind blows chillily through a doorway. The figurative use implies emotional distance deliberately maintained: unlike simple rudeness, acting chillily suggests controlled, glacial politeness that withholds warmth. The word belongs largely to written narrative prose — fiction, journalism, and formal description — where it efficiently conveys social temperature in a single syllable cluster. Its near-synonyms include icily, frostily, and frigidly, all drawn from the same metaphorical tradition of equating coldness with unfriendliness, a comparison as old as English literature itself.

The adverb of 'chilly' does double duty: it can describe a wind that cuts through your coat or a greeting that freezes a room.

Etymology of chillily
"Chillily" derives from "chilly," which was formed in the late sixteenth century from the noun "chill" plus the suffix -y. The noun "chill" comes from the Old English verbs "cile" and "ciele," related to the root of "cool," ultimately tracing back to Proto-Germanic origins shared with Dutch and German words for cold. The extended figurative sense — coldness of manner — developed alongside the adjective, so that by the seventeenth century English writers were already using "chilly" to describe unfriendly receptions, and the adverb followed naturally.
