Protoform: *ʔV(n)ʁV
Meaning: heel
Avar: eʁé
Chadakolob: eʁél
Comments: Av. paradigm C (aʁá-lzul, úʁ-dul; Chad. eʁél-dul, úʁla-l). The Chad. form has a suffixed -l. A derivate of the same root is probably the stem oʁo- in Av. oʁó-kʷer, oʁó-q:at 'palm (of hand)', Chad. oʁó-b 'span (between the thumb and fore-finger)'.
