Comment: Cf. also Lezg. pret. g-ata-na, Tab. Düb. j-at- 'beat', k-at- 'touch' ( > 'smear' in literary Tab.), Ag. Tp. ata-s 'beat', Bud. q:-ut- 'to hit (repeatedly)', Rut. k-ä=ta- 'to touch' ( = Tab. k-at-), s-ä=ta= 'to throw'. Labialisation of PL *-tʷ- is suggested by the Arch. durative form =artu-r. Not clear are the reasons for *a/ä vowel alternation. The verb belongs to the weak conjugation in PL.
