هيأ1 هَآءَ, aor. ـَ and يَهِيْءُ, (K; the latter not of respectable authority, Lh;) inf. n. هَيْئَةٌ, He was, or became, of good, or goodly, form or appearance, or other properties denoted by the term هَيْئَة, q. v. (K.) b2:  [هَيُؤَ, accord. to the K, signifies the same: but see below.] b3:  هَيُؤَ, accord. to IHsh and others, the only verb of this form whose medial radical letter is ى: (MF:) accord. to the K, syn. with هَآءَ, in a sense indicated above: but IJ states that it has a superlative sense; that it is to be classed with قَضُوَ “ excellent [or how excellent (see بَطُؤَ voce بُطَآنَ)] is he in his judging! ” and رَمُوَ “ excellent [or how excellent] is he in his throwing, or shooting! ” [wherefore it signifies Excellent, or how excellent, is he in his form or appearance! &c.;] and that it is, like قَضُوَ [and رَمُوَ], invariable [as to person, tense, and mood]. He observes that, as a verb of the measure فَعُلَ is formed from one whose final radical letter is ى, [as قَضُوَ and رَمُوَ from قَضَى and رَمَى,] so is this formed on the same measure from a verb whose medial radical letter is ى: and that it is invariable [as to person, tense, and mood,] because of its resemblance, in its superlative sense, to the class of verbs of wonder, and to نِعْمَ and بِئْسَ. He further remarks, that they [the Arabs] have abstained from forming a verb on the measure فَعُلَ [variable as to person, tense, and mood,] from one whose medial radical letter is ى, fearing to make what is difficult to pronounce still more so; for in that case they would be obliged to say أَبُوعُ بُعْتُ, and بُوعَا; and, as would also happen if a variable verb of the same measure were formed from one whose final radical letter is ى, the change of ى into و, which is more difficult to pronounce, would thus become frequent.

(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 اسْقِيَانِى 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.
