مُوسَى

[A razor;] a certain instrument of iron, (M, Msb, TA,) with which one shaves: (Lth, L, K, TA:) of the measure فُعْلَى, (Ks, M, Msb, K,) from المَوْسُ, [verbal noun of مَاسَ,] so that the م is a radical letter, (K,) according to Lth, (TA,) [for] Lth says, (L, TA,) المَوْسُ is the root (تَأْسِيس [lit. foundation]) of المُوسَى, (L, K, TA,) the thing with which one shaves; (L, TA;) therefore, (Az, Msb, K,) it is imperfectly decl., because of the short feminine ا [written ى], (Msb,) without tenween; (Az, K;) and Fr cites a verse [of obscene meaning] in which it is made feminine: (TA:) or it is from أَوْسَيْتُ رَأْسَهُ, meaning “ I shaved his head, ” (ISk, M, * Msb, K,) of the measure مُفْعَلٌ, (ISk, Msb, TA,) so that the ى is a radical letter, as El-Umawee and Yz say, and Aboo-'Amr Ibn-el-Alà inclined to think it so, (TA,) and therefore it is perfectly decl., (Msb,) with tenween, (Msb, K,) when indeterminate; (Msb;) or it is of the measure مُفْعَلٌ because this measure is more common than فُعْلَى, and because it is perfectly decl. when indeterminate, whereas فُعْلَى is not so when indeterminate and when determinate: (Ibn-EsSarráj, TA:) but IAmb says, that it is masculine and feminine, and perfectly decl. and imperfectly decl.: ISk says, that the approved way is to make it perfectly decl.: (Msb:) [but] he says that it is feminine [also, and if so it is imperfectly decl.]: (TA:) and it is related of A'Obeyd, in the Bári', that he said he had not heard it made masculine except by El-Umawee; (Msb;) who asserted it to be masculine only: (TA:) the plural, according to him who makes it imperfectly decl., is مُوسَيَاتٌ; and according to him who makes it perfectly decl., مَوَاسٍ. (Msb.) The diminutive of موسى, in the sense above explained, [not as a proper name, in which case it is مُوسَى only, without tenween, and has no relation to the same word signifying a razor,] is مُوَيْسِيَةٌ, [but by rule it should be مُوَيْسَى, like حُبَيْلَى,] according to him who says هٰذِهِ مُوسَى; and مُوَيْسٍ according to him who says هٰذَا مُوسًى. (ISk, TA.)
