Proto-North Caucasian: *ʔilsV̆
Meaning: tower
Proto-Avaro-Andian: *ʔisV Notes: Reconstructed for the PEC level. Although not very widely spread (attested only in four languages), the root is no doubt archaic. Medial -l- is reconstructed on basis of PC nasalisation, and is well confirmed by the HU parallel: Hurr. ilʒ-iri 'boundary mark of the universe (provided with a watch-tower)', see Diakonoff-Starostin 1986, 42).
