كسر

كِسْرَى ذ and كَسْرَى, (S, Msb, K,) the former of which is the more chaste, accord. to Th and others, and it alone is allowed by Aboo-'Amr Ibn-El-'Alà, (Msb,) A name (TA) applied to the king of the Persians, (Msb, K, TA,) or a surname of the kings of the Persians, (S,) like النَّجَاشِىُّ, a name of the king of Abyssinia, (TA), arabicized from خُسْرَوْ, (S, K,) which means “ possessing ample dominion, ” (K,) in the Persian language: so they say: but خُسْرَوْ is itself arabicized from خُوشْ رُوْ, which means, in that language, “ goodly in countenance ”: (TA:) [but that خسرو is an arabicized word may reasonably be doubted:] accord. to IDrst, it is changed into كسرى because there is no word in Arabic having the first letter with damm and ending with و; and the خ is changed into ك to shew that it is Arabicized: (MF:) the pl. is أَكَاسِرَةٌ, (S, Msb, K,) contr. to analogy, (S,) and كَسَاسِرَةٌ and أَكَاسِرُ and كُسُورٌ, (K,) [all of which are also] contr. to analogy: (TA:) by rule it should be كِسْرَوْنَ, like عِيسَوْنَ (S, K) and مُوسَوْنَ.
