De Vaan prefers to connect the word to Proto-Celtic *drukos (“bad”), assuming a sound change from Proto-Indo-European *dr- > Latin tr-. However, this assumes that the Celtic form derives from a Proto-Indo-European root starting with *dr- (instead of a different consonant cluster like *dʰr-), which is far from certain.
An alternative theory derives the word from Proto-Indo-European *truḱ-, a metathesis of *turḱ-, zero-grade of *twerḱ- (“to cut”). In this case, cognate with Ancient Greek σάρξ (sárx), Old Irish tru, troich (“fated to die”) and others in Sanskrit and Hittite.
