語源 1

From 中期英語 forke (“digging fork”), from 古期英語 force, forca (“forked instrument used to torture”), from Proto-West Germanic *furkō (“fork”), from Latin furca (“pitchfork, forked stake; gallows, beam, stake, support post, yoke”), of uncertain origin. The 中期英語 word was later reinforced by Anglo-Norman, Old Northern French forque (= Old French forche whence French fourche), also from the Latin. Doublet of fourche and furcate. Cognate also with North Frisian forck (“fork”), Dutch vork (“fork”), Danish fork (“fork”), German Forke (“pitchfork”). Displaced native gafol, ġeafel, ġeafle (“fork”), from 古期英語.

In its primary sense of “fork”, Latin furca appears to be derived from Proto-Indo-European *ǵʰerk(ʷ)-, *ǵʰerg(ʷ)- (“fork”), although the development of the -c- is difficult to explain. In other senses this derivation is unlikely. For these, perhaps it is connected to Proto-Germanic *furkaz, *firkalaz (“stake, stick, pole, post”), from Proto-Indo-European *perg- (“pole, post”). If so, this would relate the word to 古期英語 forclas pl (“bolt”), Old Saxon ferkal (“lock, bolt, bar”), Old Norse forkr (“pole, staff, stick”), Norwegian fork (“stick, bat”), Swedish fork (“pole”).
