مَحَاسِنُ
1.
The beautiful places [or parts] of the body: (K:) according to some, (TA,) the singular is
مَحْسَنٌ: or it has no singular: (K:) the former opinion is disapproved by ISd.: the latter is the opinion of the grammarians and of the generality of the lexicologists: and therefore, says Sb, the rel. n. is
مَحَاسِنِىٌّ; for if مَحَاسِنُ had a singular, it would be restored to the singular in forming the rel. n. (TA.) You say, فُلَانَةُ كَثِيرَةُ المَحَاسِنِ
Such a woman has many beautiful places [or parts] of the body. (TA.) And مَحَاسِنُ الوَجْهِ
وَ مَسَاوِيهِ [The beauties of the face, and its defects]: (K in article لمح:) [for] مَحَاسِنُ signifies the opposite of
مَسَاوٍ. (S.)
2.
[As opposite of مَسَاوٍ, it signifies also Good qualities of any kind: and also good actions; like حَسَنَاتٌ: agreeably with an explanation in the KL, نيكويءيها.]
