PROTO: *s_ɨ̄nŏ (~-ǝ̆)
MEANING: long bone
COMMENT: Reconstructed for the PEC level. The original meaning was probably 'long (curved) bone', with later developments > 'long bone, spine'; 'curve, angle, corner' (cf. a combination of both trends in Lezghian languages). The Avar form is somewhat strange phonetically (*s:in would be regularly expected), so it may be a borrowing from some unknown early source.
