“The semantic agreement between continental MSA and Ugaritic-Phoenician (...) might suggest that *paˁm- was the main designation of “foot” already in PS. If this assumption is correct, the meaning “hip”, normal for Akk. pēmu, must be innovative. On the other hand, the meaning of Soq. faˁm (’upper part of the back leg of goats and sheep’) comes notoriously close to that of the Akkadian lexeme. The same is true of the verbal root fˁm in Arabic (’to be thick in one’s shanks’). In such conditions, one cannot exclude that the meanings “upper leg”, “hip”, “thigh” reflect the most primitive situation, whereas generalization to “foot” took place independently in continental MSA and Canaanite.” (Kogan 2015:586-587)
