أَكْيَسٌ ذ [More, and most, acute or sharp or quick in intellect; more, and most, shrewd, clever, ingenious, skilful, knowing, or intelligent]: (Lth, ISd, A:) fem. كِيسَى (ISd) and كُوسَى: (Lth, ISd:) [in the CK, and in a MS. copy of the K, and in the text of the K as given in the TA, كِيسَى and كُوسَى, each of which is originally كُيْسَى, are said to be fems. of أَكْوَسُ; but this is evidently a mistake for أَكْيَسُ:] pl. كُوسٌ, [originally كُيْسٌ,] which is applied to women, [as well as men,] and كُوسَيَاتٌ, which is applied to women only. (Lth.) You say, هٰذَا الأَكْيَسُ [This is the more, or most, acute &c.]. (Lth.) And أَىُّ المُؤْمِنِينَ أَكْيَسُ Which of the believers is the most intelligent? (TA.) And it is said in a proverb, أَكْيَسُ مِنْ قِشَّةٍ (A) [(tropical:) More acute &c. than] a little female ape or monkey. (TA, art. قش.) And in a trad., أَكْيَسُ الكَيْسِ التُّقَى وَأَحْمَقُ الحُمْقِ الفُجُورُ (tropical:) [The most acute of acuteness is piety, and the most foolish of foolishness, or the most stupid of stupidness, is vice]. (A.) ― -b2- See also كَيِّسٌ.
