Uncertain. Per Kroonen, most likely from Proto-Indo-European *kret- (“to shake, move suddenly”), whence also the verbs *hurtoną and *hrattōną (“to rush, tumble”); cognate with Old Irish crothaim (“I shake”), Latvian kratît (“to shake out”), Lithuanian kratýti (“id.”), Latvian krist (“to fall, drop, die”), Lithuanian krìsti (“id.”), and Lithuanian kretė́ti (“to tremble (with old age)”).[2][1]
Formerly derived from Proto-Indo-European *kerd- (compare Ancient Greek κραδάω (kradáō, “I swing, brandish”), Sanskrit कूर्दति (kūrdati, “(s/he) leaps”), Proto-Celtic *kerdeti (“puts, lays; moves”)), but the root codas (PGmc *d ~ *þ versus PIE *d) do not match. Compare Proto-Germanic *herzô (“hinge”) and Old High German scerdo (“hinge”).
