Comments:VEWT 475-476, EDT 544, TMN 2, 499-500. The stem is connected - in a somewhat unclear fashion - with *tirke- 'to hitch' (derived from tiz- 'to string' in Хелимский 1986 and Дыбо 1995, 282 - but the latter should be properly reconstructed as *diŕ-, so this derivation is by no means certain). External evidence suggests that *-i- is original here; the vowel *-e- in *terkü may be due to the influence of *dēr-ke- 'to gather; equip' (see *dēr-).
