Said of travel, hardship, and the like. Also: he, or it, prevailed over him, or it.
1.1.3
قَوِىَ is [said to be] originally قَوِوَ, because it is from القُوَّةُ (I'Ak, p. 368); but Lth holds قُوَّةٌ to be [irregular,] originally قُويَةٌ.
I prefer the former opinion, and think it should be mentioned in art. قو; or I would rather head this article قو or قوى, like غو or غوى.
ISd holds قُوَّةٌ to be from قوو, like ثُوَّةٌ (see that word) from ثوو.
