1) quté, 2) quté xordan
Fr.: 1) plongon; 2) plonger
1a) An act or instance of diving.
M.E. diven "to dive, dip," O.E. dufan (strong verb) "to dive, duck, sink" and dyfan "to dip, submerge" (weak, transitive), related to → deep.
Quté is possibly Pers., since Farhang-e Asadai records it with "t" and not Ar. "tayn" (Dehxoda), although its etymology is not established. We propose ultimately from Proto-Ir. *ui-pat-, from *pat- "to fall, to fly," to which is related Pers. oft-, oftâdan "to → fall;" cf. Pashto. qupah "a dip, a dive, a plunge."
(v.intr.) To move, or extend in different directions from a common point.
M.L. divergere, from → di- "apart," variant of → dis- + vergere "to bend, turn, incline," from PIE *werg- "to turn," from base *wer- "to turn, bend" (cf.

Verâyidan, from vâ- "apart," → de-, + gerâyidan "to incline toward; to intend; to make for," infinitive of gerâ, the etymology of which is not clear. Gerâ may be a variant of Mod.Pers. kil "bent, inclined" (k/g and l/r interchanges), from PIE base *klei- "to lean, incline," cognate with L. clinare "to bend" (E. declination, inclination, etc.), Gk. klinein "to cause to slope, slant, incline," Skt. sri- "to lean," O.Pers. θray-, Av. sray- "to lean," P.Gmc. *khlinen (Ger. lehnen, E. lean).
