ETH *ʔǝgr 'foot' usually compared to this root (so [Kaye passim]) is not related; see *ʔi(n)gir-, No. .
Cf. JUD nigrā [Ja 902] <*ligr-, with dissimilation *l- > n- in the vicinity of -r-, and MND ligra 'foot, leg' [DM 235]; metathesis in both cases due to nearly complete incompatibility of r and l in SEM roots.
Cf. ESA: ḤḌR rgln 'fantassin' [LM 77], with a meaning shift.
