means The process of a liquid getting so cold it locks into a solid — or, loosely, any sensation of being painfully, stiffeningly cold.

from From Old English 'freosan,' which traces back to a very old Germanic root shared with words for 'frost' and, further back, an ancient Indo-European root meaning simply 'to freeze' or 'to burn with cold' — the same deep root that gives Latin its 'prurire'-adjacent chill words and English 'frost' and 'frigid' cousins through separate branches. The word has stayed close to its meaning for thousands of years: cold doing exactly what cold does, described plainly by people who had no central heating and very strong opinions about winter.
