The diachronic interpretation of Indo-European *hṷekṷ- / *heuk- “eye, to see”, Altaic *uka- “to notice, to understand” and Afro-Asiatic *Hwq- “to know”, originating from Nostratic *HuḲa “eye, to see”, allowed to establish both divergent and convergent types of linguistic relationship among them, for which the close (Indo-European, Altaic, Afro-Asiatic) and remote / distant (Indo-European / Afro-Asiatic and Altaic) types of language relationship have been established, depending on the action of the main phonomorphological and semantic regularities.The degree of manifestation of phonomorphological laws indicates a close type of language relationship among Indo-European, Altaic and Afro-Asiatic language families. They are: 1) the law on the three-letter / three-phonemic root structure of an archetype (according to E. Benvenist), which corresponds to the law on the consonant root (according to A G. Belova): it helped to fix three phonemes in Indo-European *hṷekṷ- / *heuk-, Altaic *uka- and Afro-Asiatic *Hwq-, as well as to trace the reflexes of this structure in the genetic data material of these language families; 2) the law of the mora is fixed in the Indo-European *hṷekṷ- / *heuk-, Altaic *uka- and Afro-Asiatic *Hwq-, the forms of which correspond to a monosyllable structure, and mono- and multisyllable structures have been observed in the genetic data material; 3) the process of spirantisation consists in weakening the consonant phoneme /q/, i.e. the reflection /q/ into /k/ and /x/; 4) the process of “pharyngisation” can be traced at the end of monosyllabic words, where it could occur by analogy with those forms of the word where the consonant was intervocal; 5) the law on the pronunciation of short vowel phonemes /a/ and /u/, where such features are represented: 1) the degree of solution of the oral cavity; 2) hardness / softness (low tonality / high tonality); 3) absence or presence of labilisation; 6) the law of prosody, which consists in the realisation of stress in accordance with various languages; 7) the law of an open syllable.The degree of phonomorphological manifestations indicates a remote / distant form of language relationship between Indo-European / Afro-Asiatic and Altaic language families, where one of the provisions of the phonetic prohibitions of Jucquо, i.e. when the initial and final laryngals are not allowed, is traced in the Indo-European *hṷekṷ- / *heuk- and Afro-Asiatic *Hwq-.The degree of manifestation of semantic laws indicates a close type of language relationship among Indo-European, Altaic and Afro-Asiatic language families, where 2 lexico-semantic variants (LSV) were fixed: 1) somatism; 2) action. If in the Indo-European *hṷekṷ- / *heuk- “eye, to see” 2 LSVs are fixed: 1) somatism; 2) action, but in the Altaic *uka- “to notice, to understand”, including Turkic *uk(ā)- “to raise, to listen” and Mongolian *uk- “to notice”, as well as the Afro-Asiatic *Hwq- “to know” – only 1 LSV – 2) action.
