• (RP) IPA: /wɔːm/
• (America) IPA: /wɔɹm/

From Middle English warm, werm, from Old English wearm, from Proto-West Germanic *warm, from Proto-Germanic *warmaz, with different proposed origins:

1. Proto-Indo-European *gʷʰer-, related to Ancient Greek θερμός, Latin formus, Sanskrit घर्म.
2. Proto-Indo-European *wer-, related to and to Church Slavic варити.

   The dispute is due to differing opinions on how initial Proto-Indo-European *gʷʰ- evolved in Germanic: some think that *gʷʰ would have turned to *b, and that the root *gʷʰer- would instead have given rise to burn etc. Some have also proposed a merger of the two roots.
