طوب

طُوبٌ ذ Baked bricks; syn. اآجُرٌّ: (S, O, Msb, K:) n. un. with ة: so says Az, and El-Fárábee says the like; and accord. to them it seems to be [genuine] Arabic: accord. to IDrd, it is of the dial. of Syria; but [Fei adds] I think it to be of the dial. of Room: (Msb:) or it is of the dial. of Egypt: (S, O:) [probably of Coptic origin. It is mentioned in the S and K in art. طيب.]
