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 from the present stem by analogy.
Cognate with Lithuanian tèpti (“to smear, grease”). Only Balto-Slavic, without other Indo-European cognates.
