Reconstruction:Proto-Slavic/teti

• *tepti
• *tepsti

From Proto-Balto-Slavic *teptei, with a regular loss of medial *-p- in the infinitive stem due to the law of open syllables. p has been restored in many of the daughters by analogy with the present stem, and s has been inserted into the infinitive in many of the daughters by analogy with other verbs in -sti. Compare *greti (“to dig, to rake”).

Cognate with Lithuanian tèpti (“to smear, to grease, to soil”) (1sg. tepù), Latvian tept (“to smear, to grease”) (1sg. tepju).

• Per Derksen, only Balto-Slavic, without other Indo-European cognates.
• Vasmer adds as cognates Lithuanian tapýti (“to sculpt”) (1sg. tараũ), Lithuanian tapnóti, tapšnóti (“to pat with the hand”). In addition, he asserts that dialectal Russian тепсти́ (tepstí, “to pull, to drag”) is etymologically distinct, related to Lithuanian tem̃pti (“to pull”) (1sg. tempiù), temptýva (“string”), Russian тетива́ (tetivá, “string”), Lithuanian tampýti (“to pull”) (1sg. tampaũ).
