Reconstructed for the PEC level. Correspondences are regular. Cf. also the HU parallels: Hurr. lula-χ:ǝ 'foreigner' ( = PN *lōlu-χaw), Ur. lul-ue 'foreigner, enemy' (see Diakonoff-Starostin 1986, 48). Abdokov (1983, 88) compares the Andian forms (with the secondary meaning 'parent-in-law') with Ad. ṣʷǝ- in ṣʷǝ-gʷāš́ 'mother-in-law', ṣʷǝ-pš́ 'father-in-law'. These forms, however, being quite isolated in WC, should be rather analyzed as metaphoric compounds meaning originally 'fair princess'/ 'fair prince'; at any rate, Ad. ṣʷ- (going back to PWC *c̣ʷ) can not correspond to PEC *Ł_.
