Comment: Cf. also Bud. term. ʕake-ǯi, Arch. dur. =erku-r, Ag. Bursh. alt:-arki- 'to fall; to lie down, go to bed' (also ut:-arki-, ʁ-arki-, ʕ-arki-). Without a preverb cf. Ag. Bursh. arki- 'to fall down'; all other languages use only the root combined with preverbs. The verb belongs to the strong conjugation class. It should be distinguished from PL *ʔarke- 'to go, move (away)' q.v. (although sometimes contaminations are happening).
Most forms reflect the PL vowel *-a- in the first syllable; Archi, however. reflects *-e-. Cf., perhaps, also Tab. -e=k- in k:-e=k- 'to hide, to conceal' (*'to put down, to let lie') and with some other preverbs.
