مَرْسِنٌ ذ (S, M, K) and مَرْسَنٌ, (M, K,) or the latter should be مِرْسَنٌ, [but I think this doubtful,] thus written in some of the copies of the S, and in both ways in the L, (TA,) The part, of the nose of the horse, which is the place of the رَسَن: (S:) or the nose of a solid-hoofed animal: this is the primary signification: (M:) then, by a secondary application, (S, M,) the nose (S, M, K) in an absolute sense, (M, K,) or, of a human being: (S:) pl. مَرَاسِنُ (TA) [which, as stated by Freytag, is used in a sing. sense, in the Deewán of Jereer, as meaning the nose ]. سَلِسُ المَرْسِنِ, a phrase used by the poet El-Jaadee, means (assumed tropical:) Easy to be led, tractable, or compliant. (TA.) And you say, فَعَلْتُ ذٰلِكَ عَلَى رَغْمِ مَرْسِنِهِ (assumed tropical:) [ I did that against his wish; in spite of him; or notwithstanding his dislike, or disapproval, or hatred; like as you say, عَلَى رَغْمِ أَنْفِهِ]. (S.)
