(M, K.) ― -b2- (tropical:) He [a horse) outreached the other horses with his chest; (M, K, * TA;) as also ↓ صدّر, (S, * M, MA, K,) inf. n. تَصْدِيرٌ: the latter verb is afterwards expl. in the K as meaning بَرَزَ بِرَأْسِهِ; but this is a mistake. (TA.) Tufeyl says, describing a horse, مِنْ عَرَقٍ ↓ كَأَنَّهُ بَعْدَ مَا صَدَّرْنَ سِيدٌ تَمَطَّرَ جِنْحَ اللَّيْلِ مَبْلُولُ As though he were, after they had outreached with their chests, from a row of [other] horses, [ a wolf that had exposed himself to rain during a portion of the night, and had become wetted: ] but accord. to one relation, it is ↓ صُدِّرْنَ, meaning their breasts were wetted [مِنْ عَرَقٍ] by reason of sweat: the former reading, however is the better. (S.) ― -b3- Also (assumed tropical:) He sat, or became placed or seated, in the upper, or highest, part in the sitting-room, or sitting-place. (S, * K, * TA.) And He became advanced, or promoted. (A.) تصدّر لِأُمُورِ النَّاسِ (assumed tropical:) [ He became advanced to the foremost place for the conducting of the affairs of the people ]. (Har p. 194.)
