What does frostier mean?
Frostier is the comparative form of the adjective frosty, indicating either a lower degree of temperature — literally, weather that is colder or more heavily coated with frost — or, figuratively, a manner or atmosphere that is more unfriendly, reserved, or strained. In literal use it describes conditions such as 'a frostier morning' or 'frostier roads', while in social contexts it characterises receptions, glances, relationships, or negotiations that have grown noticeably colder. The word appears frequently in news reporting and political commentary, where shifts in diplomatic warmth are often described in thermal terms. Because it is a comparative, it implies a point of comparison: something has become frostier than before, or one thing is frostier than another. Its connotations are mildly negative in interpersonal use but neutral in weather descriptions. Related forms include the base adjective frosty and the superlative frostiest.

Etymology of frostier
Frostier descends from 'frost', an Old English word (frost, related to 'forst') of Germanic origin, found across Germanic languages and connected to Old Norse 'frost'. The adjective 'frosty' developed from this noun, and 'frostier' is simply its regular comparative formation using the -er suffix, a pattern inherited from Old English comparatives. Cognates include German 'Frost' and Old Norse 'frostr', all tracing back to a shared Proto-Germanic root.
