عُشْرٌ
1.
(S, O, Msb, K) and
عُشُرٌ (TA) A tenth; a tenth part; one part of ten parts; as also
عَشِيرٌ and
مِعْشَارٌ; (S, O, Msb, K;) which last is [of a form] not used [to denote a fractional part] except as applied to the tenth part (S, O) and [in the instance of مِرْبَاعٌ applied to] the fourth part: (O:) or, as some say, مِعْشَارٌ is the tenth of the tenth [i. e. a hundredth part]: and as some say, مِعْشَارٌ is the tenth of the
عَشِير, which latter is the tenth of the
عُشْر; so that, according to this, the معشار is one of a thousand; for it is the tenth of the tenth of the tenth: (Msb:) [in the TA, “ and as some say, معشار is plural of عشير, which latter is plural of عُشْرٌ: ” but this is evidently a mistake:] the plural of عُشْرٌ is أَعْشَارٌ (Msb, K) and عُشُورٌ; (K;) and that of
عَشِيرٌ is أَعْشِرَاءُ: (S, O, Msb:) it is said in a tradition, تِسْعَةُ أَعْشِرَاءِ الرِّزْقِ فِى التِّجَارَةِ وَجُزْءٌ مِنْهَا
فِى السَّابِيَاءِ, i. e. [Nine tenths of the means of subsistence consist in merchandise, and one part of them consists in] the increase of animals. (S, A, * O. *)
