Probably from otherwise lost Proto-Balto-Slavic *témptei (“to pull”) + *-iva (whence Lithuanian tem̃pti (“to pull, to drag”), Latvian tìept (“to strain”)), ultimately from Proto-Indo-European *ten- (“to stretch”). Cognate with Lithuanian temptýva (“stretching”), ti̇̀mpa (“sinew”), possibly Old Norse þǫmb (“bowstring”), Old Armenian թամբ (tʻamb, “saddle”) and further akin to Lithuanian tiñklas (“set”), Ancient Greek τένων (ténōn, “tendon”), New Latin tensor.

* -asъ is the expected Balto-Slavic form but is found only in some Old Czech documents; -axъ is found everywhere else and is formed by analogy with other locative plurals in -xъ.
** The second form occurs in languages that contract early across /j/ (e.g. Czech), while the first form occurs in languages that do not (e.g. Russian).
