نَاعِسٌ
1.
, particle n. of نَعَسَ, [Drowsing, drowsy, or heavy with sleep: or slumbering, or dozing:] (S, Msb, K:) as also
نَعْسَانٌ; (Lth, Fr, Th, Msb, K;) but this latter is rare; (Fr, Th, Msb, K;) and by some disallowed: (TA:) feminine of the former with ة: (Msb, TA:) and of the latter نَعْسَى, made to accord. with وَسْنَى, feminine of وَسْنَانٌ; and this is best in poetry: (Lth, Msb, TA:) and
نَعَّاسَةٌ is also used as an epithet [in an intensive sense] applied to a female: (TA:) the plural of نَاعِسٌ is نُعَّسٌ; like رَكَّعٌ, plural of رَاكِعٌ: and that of نَاعِسَةٌ is نَوَاعِسُ. (Msb.)
