ه ي ء

Apparently denominal from هَيْئَة‎ (hayʔa), compare طَرْز‎ (ṭarz) for an equal development. The Dictionnaire du faisceau dialectal arabe andalou suggests an Old South Arabian borrowing, in view of Sabaean 𐩠𐩺𐩲‎ (hyʿ /hayaʿa/, “to flow, to run; to extend (boundary); to carry out, to implement or accomplish (construction)”), which is indeed with a voiced pharyngeal fricative instead of a voiceless glottal plosive here and in derivations, and possibly related to ش ي ع‎ (š-y-ʕ) related to spreading.
