قبط

قُبْطِىٌّ ذ A kind of thin, or fine, (Mgh, Msb,) white, (Mgh,) cloth, (Mgh, Msb,) of linen, (Msb,) made in Egypt; so called in relation to the قِبْط, irregularly, to distinguish between it and the man, who is called قِبْطِىٌّ: (Mgh, Msb:) so says Lth, respecting these two forms: (TA:) you also say, ↓ ثِيَابٌ قِبْطِيَّةٌ, with kesr; but when you convert the rel. n. into a subst, you say قُبْطِيَّةٌ, with damm, to distinguish the subst. from the rel. n. without ثياب; like as you say, رِمَاحٌ خَطِّيَّةٌ, and خِطِّيَّةٌ, with kesr, when you do not mention the رماح: so says Kh: (Msb in art. خط:) it is said in the K, that القُبْطِيَّةُ, with damm, signifies a kind of cloths, so called in relation to the قِبْط; and sometimes it is with kesr; which is a plain assertion that the form with damm is the more common: but in the S it is said, that القِبْطِيِّةُ signifies certain white, thin, or fine, cloths, of linen, made in Egypt; and sometimes it is with damm, because they make a change in the rel. n., as in سُهْلِىٌّ and دُهْرِىٌّ, which (as SM adds) are from سَهْلٌ and دَهْرٌ; and this indicates that the regular form, with kesr, is the more common: (TA:) the pl. is قَبَاطِىٌّ (S, Mgh, Msb, K) and قَبَاطِى: (K [but the latter, being indeterminate, should be written قَبَاطٍ, like مَهَارٍ &c.:]) Sh says, that the قَبَاطِىّ are a kind of cloths inclining to fineness and thinness and whiteness.
