History
From Middle English firre, from Old English fyrh, furh, as in furhwudu (“pinewood”), from Proto-West Germanic *furhu, from Proto-Germanic *furhō, *furhijǭ, from Proto-Indo-European *pŕ̥kweh2, from *pérkwus (“oak”). Possibly conflated during Middle English with Old Norse fýri (as in fýriskógr (“pine-wood”). Germanic cognates include Dutch vuren, Low German Fuhr, German Föhre (“pine”), Danish fyr). Outside of Germanic, compare Italian (Trentino) porca (“fir”), Latin quercus (“oak”), Albanian shpardh, shparr (“Italian oak”), Punjabi ਪਰਗਾਇ (pargāī, “holm oak, Quercus baloot”)). Related to frith.
