حَسُنَ , (S, Mgh, Msb, K, &c.,) which may also
be written and pronounced حَسْنَ, with the dammeh
suppressed, (S,) and حَسَنَ, (K,) aor.
حَسُنَ , (TA,) inf. n.
حُسْنٌ (S, * Msb, K, * TA) and حُسْنَى, (Ham p. 657,
and Bd in ii. 77,) He, or it (a thing, S, Msb),
had, or possessed, the quality termed حَسْنٌ [which
see below; i. e., was, or became, good, or goodly,
(generally the latter,) beautiful, comely, or pleasing,
&c.; and ↓ تحسّن often signifies the same, as in
the phrase تحسّن عِنْدَهُ it was, or became, good,
&c., in his estimation]: (S, K, TA:) and [in like
manner] زَيْدٌ ↓ أَحْسَنَ means Zeyd became possessed
of حُسْن. (Mughnee in art. بِ.) ―
2-b2- One may not
say حُسْنَ, transferring the dammeh of the س to
the ح and making the former letter quiescent,
except in one case; because it is [virtually, together with its agent expressed or implied, in this
case,] a predicate: [see I'Ak p. 234:] this is
allowable only in the case of a verb of praise or
dispraise; حُسْنَ, in respect of the transference of
the medial vowel, being likened to نِعْمَ and بِئْسَ,
which are originally نَعِمَ and بَئِسَ: and thus one
does in all verbs like these two in meaning: a
poet says,
لَمْ يَمْنَعِ النَّاسُ مِنِّى مَا أَرَدْتُ وَ مَا
أُعْطِيهِمُ مَا أَرَادُوا حُسْنَ ذَا أَدَبَا
[Men have not withheld from me what I have
desired, nor do I give them what they have desired: good, or very good, is this as a mode of conduct!]: meaning حَسُنَ هٰذَا أَدَبًا. (S, TA.) You
say also, حَسُنَ زَيْدٌ, [meaning Good, or goodly,
&c., or very good &c., is Zeyd! or] meaning
بِهِ ↓ أَحْسِنْ [i. e. how good, or goodly, &c., is Zeyd!
as also ↓ مَا أَحْسَنَهُ]. (B, TA in art. بِ.)
