Uncertain. Two different etymologies have been proposed.

  1. From Proto-Indo-European *gʷʰór-mo-s, from *gʷʰer- (warm, hot) +‎ *-mos, related to Ancient Greek θερμός (thermós), Latin formus, Persian گرم(garm) and Sanskrit घर्म (gharma).[1]
  2. From Proto-Indo-European *wór-mo-s, from *wer- (to burn) +‎ *-mos, related to Hittite [script needed] (warnuzi).[2]

The dispute is due to differing hypotheses on how Proto-Indo-European initial *gʷʰ- evolved in Germanic. Some maintain that *gʷʰ would have turned to *b, and therefore that the root *gʷʰer- would instead have given rise to *ber- (to burn) etc. (compare *banô < *gʷʰon-ō). A counterargument (e.g. Kroonen (2013: p. xxviii)) is that Germanic *w is in fact the usual outcome of *gʷʰ, citing uncontroversial examples such as *snaiwaz < *snóygʷʰos and *neurô < *négʷʰrō. There have also been etymologies proposing a merger of the two roots.
