γνάμπτω

Etymology
. Although it is commonly assumed that it was influenced by, this verb does not have the κ-, nor can the -ν- have been taken from there. An Indo-European etymology seems excluded, because γναμπ- cannot have an Indo-European preform. Even though an alternation γν/κ is not typical for either, Beekes does not reject this hypothesis.

Verb

 * 1) to bend
