What does chilliness mean?
Chilliness is a noun with two closely related senses: it refers to the physical quality of being uncomfortably cold, as in the chilliness of an unheated hallway on a winter morning, and, by extension, to an emotional coldness — a manner or atmosphere that feels unfriendly, reserved, or unwelcoming. The word derives from 'chilly', itself formed from 'chill', an old Germanic-rooted term for cold. In its literal sense, chilliness suggests a moderate but noticeable cold rather than extreme freezing conditions. In its figurative sense, it often describes interpersonal dynamics: a host's chilliness toward a guest, or the chilliness that pervades an awkward meeting. The figurative use is common and well established in both British and American English, reflecting the long-standing metaphorical link between warmth and friendliness. Slightly formal in tone, chilliness appears frequently in descriptive and literary writing.
The state or quality of being uncomfortably cold; a noticeable lack of warmth in temperature.
"The chilliness of the cellar kept the wine perfectly preserved."
Refers to moderate rather than extreme cold; for intense cold, words like 'freezing' or 'bitterness' are more typical.
A manner, reception, or atmosphere characterized by unfriendliness or emotional distance.
"He was discouraged by the chilliness of her response to his proposal."
Rarely used in the plural; the singular is standard even when referring to multiple instances, e.g. 'several moments of chilliness'.
"The novel captures the small chillinesses that creep into a fading marriage, though most writers would phrase this differently."
Chilliness does double duty: it can describe a freezing room or a frosty handshake — English lets temperature and temperament share one word.

Etymology of chilliness
Chilliness is formed from the adjective 'chilly' plus the noun-forming suffix '-ness'. 'Chilly' derives from 'chill', which comes from Old English 'cele' or 'ciele' meaning cold, a word of Germanic origin related to the root seen in 'cold' and 'cool'. The compound form 'chilliness' has been used since at least the early modern period to describe both physical coldness and emotional distance, extending the familiar metaphor that equates warmth with kindness.
