قَدْحٌ خَيَّابٌ
1.
(tropical:) [An endeavour to produce fire with a زَنْد] that does not produce fire (لَايُورِى). (A, K. * [In some copies of the K, for قَدْح, we find قِدْح. Golius explains خَيَّابٌ as meaning ignitabulum fallens, quod non excudit semina ignis: but I cannot anywhere find قَدْحٌ or قِدْحٌ in the sense which he assigns to one of these words, which is that of مِقْدَحَةٌ &c.])
2.
In the following verse, quoted by Th,
حيّاب may be [an epithet] of the measure فَعَّال from الخَيْبَةُ; [so that the meaning may be (assumed tropical:) Be thou silent, and speak not, for thou art habitually unsuccessful; thou art altogether vitious, or faulty, and thou art a great imputer of vices, or faults, to others;] or the person there men tioned may be meant to be likened to the قدح above mentioned. (TA.)اُسْكُتْ وَلَا تَنْطِقْ فَأَنْتَ خَيَّابْكُلُّكَ ذُو عَيْبٍ وَأَنْتَ عَيَّابٌ
