What does cosie mean?
"Cosie" describes something warm, comfortable, and inviting — a firelit room, a thick blanket, a quiet café on a rainy afternoon. It is essentially a British variant spelling of "cosy," the form standard in the United Kingdom, while American English writes the same word as "cozy." The word functions chiefly as an adjective, though English also uses the noun form for a padded teapot cover (a tea cosy) and the informal verb phrase "cosie up" for snuggling close or ingratiating oneself. Its connotations are overwhelmingly pleasant, evoking domestic warmth and intimacy, though it can take on a faintly critical edge when applied to overly comfortable arrangements between people or institutions. The word's origin is uncertain, but it has been part of English since at least the early eighteenth century, likely emerging from Scottish usage before spreading widely. For anyone writing about comfort, home, or atmosphere, "cosie" — in whatever spelling — remains an indispensable and evocative term.
Warm, comfortable, and snug; giving an impression of homely ease and contentment.
"We settled into the cosie inglenook by the fire and stayed there all evening."
Chiefly British; "cozy" is the usual spelling in American English, and "cosy" is more common than "cosie" even in Britain.
A padded cover placed over a teapot or other vessel to keep its contents warm, most familiar as the tea cosy.
"She lifted the cosie off the pot and poured out two cups of tea."
In this sense the plural is "cosies."
To make oneself snug or comfortable, used especially in the informal phrase "cosie up" (to cuddle close or seek favour with someone).
"The kittens cosied up against their mother to escape the draught."
Informal; far more often encountered as the phrasal form "cosie up" than as a standalone verb.
Applies to the noun sense (a padded cover, especially for a teapot). The adjective does not have a plural form in ordinary use.
"The shelf by the stove was lined with knitted cosies in every colour."
One little word, at least three spellings — cosie, cosy, and cozy all snuggle up to the same meaning.

Etymology of cosie
The origin of "cosie" (usually spelled "cosy") is uncertain, and dictionaries have offered several speculative sources without settling definitively on one. The word is generally thought to have entered standard English in the early eighteenth century, with some of its earliest recorded uses appearing in Scottish writing. Whatever its ultimate source, it quickly established itself as the standard British term for snug comfort, later spawning the noun "tea cosy" in the nineteenth century, while American English adopted the spelling "cozy."
