temno.

Disputed. * Rix lists the term as a derivative of Proto-Indo-European *tm̥-ne-h₁-ti, a nasal-infix from *temh₁- (“to cut”). * De Vaan argues that temnō is likely a back-formation from contemnō, as contemnō has much older attestations than temnō. De Vaan agrees, however, that the ending -temnere most likely derives from a nasal-infix of the root *temh₁- (“to cut”). Though, De Vaan suggests that it could also be explained from *stemb- (“shake violently”). * The linguist Gerhard Meiser has suggested that the perfect form -tempsī emerged via the contamination of a possible s-aorist belonging to the root *stemb-. However, the form could have emerged without any such influence, as perfect stems marked by *-psī emerged in many Latin verbs ending with a labial stop.
