dial. of El-Hijáz, and of which the inf. n. is عَثًا;

فِى الأَرْضِ [in the earth]: (S, TA:) the aor. of
one of the dial. vars. occurs in the Kur ii. 57;
&c.: some say that عثا, aor. يعثا, [or عِثَى, aor.
يَعْثَى,] is formed by transposition from عَاثَ, aor.
يَعِيثُ: (TA:) accord. to Er-Rághib, عَيْثٌ and
عُثِىٌّ, or عِثِىٌّ, and عُثُوٌّ are nearly alike; but عَيْثٌ
is mostly used in relation to that which is
perceived by sense; and عثىّ and عثوّ, in relation
to that which is perceived by the [mind or]
judgment: some say that عثوّ [as also عثىّ] is the
acting wrongfully, injuriously, or unjustly; and
sometimes does not involve the acting corruptly:
(MF and TA in art. عيث:) Lh says that عَثِىَ
is of the dial. of El-Hijáz, and is the [more]
approved form; and عاث is of the dial. of the
Benoo-Temeem. (TA in that art.) ―
