κυφός

Clearly related to κύπτω (kúptō, “to stoop”). According to Beekes, the variation "κυφ-/κυπ-" points to a Pre-Greek origin. However, the word shows phonetic and semantic similarities with other terms across Indo-European, such as Sanskrit कुभ्र (kubhrá, “humpbacked bull”), कुब्ज (kubjá, “humpbacked, crooked”) (though the Sanskrit terms have also been derived from Munda, precluding connection with the Greek), and Proto-Indo-Iranian *kʰumbʰas (“pot”), as well as Lithuanian kuprà (“hump”) and Old High German hovar (“hump”) (which show root-final *-p-, making a relation more difficult).^[1]
