قوى

1 قَوِىَ ذ and ↓ تَقَوَّى (S, K) and ↓ اِقْتَوَى (K) He became strong: (S, K:) vigorous, robust, or sturdy; like اِشْتَدَّ, or the last signifies he became excellent in strength. (TA.) ― -b2- قَوِىَ عَلَيْهِ He had strength, or power, sufficient for it; or he had strength, or power, to endure it; he prevailed against it; namely, travel, adversity, &c. And He or it, prevailed over him, or it. ― -b3- See 4. ― -b4- قَوِىَ is [said to be] originally قَوِوَ, because it is from القُوَّةُ: (I'Ak, p. 368:) but Lth holds قُوَّةٌ to be [anomalous,] originally قُويَةٌ. (TA.) I prefer the former opinion, and think it should be mentioned in art. قو, or I would rather head this art. قو or قوى, like غو or غوى. ISd holds قُوَّةٌ to be from قوو, like ثُوَّةٌ, q. v. from ثوو.
