استحسنهُ

He counted, accounted, reckoned, or esteemed, him, or it, حَسَن [i. e. good, goodly, beautiful, comely, pleasing, &c.; he approved, thought well of, or liked, him, or it]; (S, K;) as also ↓ حسّنهُ, verbal noun تَحْسِينٌ. (Har p. 594.) Hence the saying, صَرْفُ هٰذَا اسْتِحْسَانٌ وَ المَنْعُ قِيَاسٌ [The making this word perfectly declinable is approvable, but the making it imperfectly declinable is agreeable with analogy]. (TA.)
