The origin of Proto-MSA *madram- heel ‘heeľ is uncertain (Kogan 2015:552). Comparison with Arb. drm ‘to be even, to have no protruding parts’ suggested in GD 767 is semantically problematic, although it is noteworthy that the Arabic root is mostly applied to parts of the body (notably, to ˁurqūb- ‘Achilles’ tendon’). Cf. also Arb. drm ‘to move slowly; to move with small steps (like a hedgehog or a hare)’. Note, finally, Syr. mdarram ‘astutus’, mdarmutā ‘astutia, improbitas, machinatio’, which may be of interest in view of a similar semantic correlation in Hbr. ˁāḳēb ‘heeľ — ˁḳb ‘to betray’.
