طُيَّابٌ

, with damm, means طَيِّبٌ جِدًّا [i. e. Very good, pleasant, delightful, delicious, sweet, or savoury]. (S, O, TA. [In the K it is implied that it is simply synonym with طَيِّبٌ; like as many other intensive epithets are confounded therein with those that are not intensive.]) A poet says,

إِنَّا وَجَدْنَا مَاءَهَا طُيَّابَا

[Verily we found its water to be very good, pleasant, or sweet]. (S, O.)
