Comment: In Archi cf. also heIrša-s (dur. heIršu-r) 'to run' (from the Ablaut grade *häšʷä- with a durative infix). The MSU spelling is heIrš:a-s, but the word is impossible to separate from šeI-s 'to run away' (connected like qIe-s : heIrqIa-s 'to go, walk'), thus the tenseness of -š:- is either misspelled or expressive (another solution would be a contamination with PL *[š:ʷ]ar- q.v.). Cf. also Ag. at:-iš- 'to jump', perhaps also ʁa-jša- 'to stand up'.
