هيء

يَا هَىْءَ مَا لِى ذ [but see شىءٌ] [ Oh! what has happened to me? ] an expression of regret; هَىْءٌ being a word signifying regret for a thing that passes away from one, or escapes him: (S, TA:) or, (as some say, TA,) an expression of wonder: (K:) see also يَاشَىْءِ and يَافَىْءَ, which are syn. with يَاهَىْءَ: (TA:) or هَىْءَ, (accord. to certain of the lexicologists, as related by IB, TA,) is an imperative verbal noun, signifying Attend! (تَنَبَّهْ); like صَهْ, which signifies “ Be silent! ” (K;) the interjection يا being put before it in like manner as it is in the saying of Esh-Shemmakh, أَلَا يَا ا@سْقِيَانِى قَبْلَ غَارَةِ سَنْجَالِ [ Come now! O, give me to drink, before the expedition of Sinjáb! ]; (TA;) and هىء being indeclinable, with a vowel for its termination to obviate the occurrence of two quiescent letters, and with fet-hah as the final vowel because it is more easy of pronunciation than the others in this case. (K, TA.) ― -b2- [See also art. شيأ.]
