سَاكِفٌ

The lintel of a door, in which turns the صَايءِر, (O, K, TA,) this latter word meaning [the upper and] the lower extremity of the door, the upper of which turns [in a socket in the lintel, and the lower in a socket in the threshold]: so says En-Nadr. (O, TA. [The explanation of صَايءِرٌ in the O seems to have been mutilated by a copyist, and requires the additions which I have made, according to modern usage.])
