Etymology
Of uncertain origin.
In its primary sense of "fork", 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 the other senses, this derivation is unlikely. For those, 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 Old English forclas pl (“bolt”), Old Saxon ferkal (“lock, bolt, bar”), Old Norse forkr (“pole, staff, stick”), Norwegian fork (“stick, bat”), Swedish fork (“pole”).
Compare also Lithuanian žer̃gti (“to spread the legs”), žìrklės (“scissors”), though the mismatch of the vowels between the Lithuanian and Latin forms is hard to explain.[1]
