صُفَّة [i. e. porch, or roofed vestibule, or the like], (S, K,) similar to an
أَزَج [or oblong arched or vaulted structure, or a portico], (T, S, M, K,) or built in the form of an
أَزَج, (Msb,) not closed in the front, or face: (T, M, Msb: *) [and a palace; often used in this sense in Arabic as well as in Persian: and in the present day, the former, and more commonly لِيوَان, which is Persian, is also applied to an estrade; a slightly-raised portion of the floor, generally extending nearly from the door to the end, or to each end, of a room:] plural of the former, أَوَاوِينُ, (T, S, K,) because the singular is originally إِوْوَانٌ, (S,) and إِيوَانَاتٌ; and plural of the latter, أُونٌ. (T, S, K.) Hence, إِيوَانُ كِسْرَى [The great porch, or the palace, of Kisrà, or Chosroes, who is called صَاحِبُ الإِيوَانِ]. (T, S, Msb.)
