يرنأQ. 1 يَرْنَأَ لِحْيَتَهُ (K, TA; in the CK, [erroneously,] تَرَنَّأَ;) He dyed his beard with يرنّأ. (K.) A strange verb as to its form, (K,) which  [except in its final vowel] is that of an aor. st, though it is a preterite. (TA.) Mentioned in the L in art. رنأ (q. v.), on the authority of IJ; and there also by ISd; and AHei and others assert the ى to be augmentative. [If so, the verb is a quasi-quadriliteral-radical word.] F  follows Sgh, in mentioning it here. (TA.) يُرَنَّأٌ (S, K) and يَرَنَّأٌ and يُرَنَّآءٌ (K) and يُرَنَّا (without ء) and (accord. to [the Bári', as mentioned in] the TA, art. رنأ,) يَرْنَأٌ and يُرْنَأٌ and (accord. to MF, who omits the two forms here immediately preceding,) يَرَنَّاءٌ and يَرَنَّا, without ء, (TA,) i. q. حِنَّاءٌ (S, K) [The plant Lawsonia inermis]. See also art. رنأ, where the word is written [erroneously in my opinion] يَرُنَّأٌ. Accord. to IB (not IJ [as in the CK]), the may only be omitted when the word is pronounced with dammeh to the ى. (TA.)
