تَرَّاعٌ
1.
A torrent filling the valley; as also
أَتْرَعُ: (K:) or a torrent which fills the valley: (S:) and ↓ the latter, a vehement torrent. (TA.) J says, in the S, that
سَيْرٌ أَنْزَعُ signifies شَدِيدٌ; and he cites the words of a poet thus:
ascribed by some to El-'Ajjáj, but correctly, according to IB, the words of Ru-beh; making two mistakes, in saying افترش, in the singular, and بسير: moreover, the last word in the citation is a pret. verb: [the right reading is]فَافْتَرَشَ الأَرْضَ بِسَيْرٍ أَتْرَعَا
[And they travelled the land with a multitude like a torrent that filled the valleys]: the poet describes the Benoo-Temeem, and their travelling the land like the torrent by reason of multitude. (Sgh, TA.)فَافْتَرَشُوا الأَرْضَ بِسَيْلٍ أَتْرَعَا
