زَهُوقٌ
1.
(tropical:) A thing passing away, or coming to nought; or that passes away, or comes to nought; as also
زَاهِقٌ. (K, TA.) Hence, in the Qur'an, 17:83, إِنَّ البَاطِلَ كَانَ زَهُوقًا, i. e. (tropical:) [Verily what is false, or vain,] is a thing that passes away, or comes to nought. (TA.)
2.
(tropical:) A deep well; (JK, S, K;) as also
زَاهِقَةٌ; [in the TA زَاهِقٌ;] and in like manner both are applied to a place of destruction (مَتْلَفَةٌ); (JK;) and to a مَتْلَفَة [apparently meaning a desert in which people perish] as meaning far-extending. (Ham p. 23.) And in like manner, (S,) the former is also applied [apparently as an epithet] to a فَجّ [or road, or depressed road,] of an overpeering, or overhanging, mountain. (S, K.)
3.
Also (tropical:) Light, or active; synonym خَفِيفٌ. (JK.)
