Etymology tree Proto-Germanic *warmaz Proto-West Germanic *warm Old English wearm Middle English warm English warm From Middle English warm, werm, from Old English wearm, from Proto-West Germanic *warm, from Proto-Germanic *warmaz, from one of: * Proto-Indo-European *wór-mo-s, from *wer- (“to burn”), which is related to Hittite 𒉿𒊏𒀀𒉌 (warāni, “to burn”), Armenian վառել (vaṙel, “to burn, heat, warm”), Old Church Slavonic варити (variti, “to cook, boil”). * Proto-Indo-European *gʷʰor-mo-s, from the root *gʷʰer- (“warm, hot”), in which case cognate with Ancient Greek θερμός (thermós) (making perhaps a distant doublet of thermos), Latin formus, Sanskrit घर्म (gharmá). In any case cognate within Germanic to West Frisian waarm, Saterland Frisian woorm, Dutch warm, German warm, Swedish varm, Icelandic varmur.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
