غَدِيرٌ
1.
A pool of water left by a torrent: (A 'Obeyd, S, M, K:) of the measure فَعِيلٌ in the sense of the measure مُفَاعِلٌ, from غَادَرهُ, or مُفْعَلٌ, from أَغْدَرَهُ; or, as some say, of the measure فَعِيلٌ in the sense of the measure فَاعِلٌ; (S;) because it is unfaithful to those who come to it to water, failing when much wanted: (S, * TA:) but it is a subst.; [not an epithet; or an epithet in which the quality of a subst. predominates, and only used as a subst.:] you do not say هٰذَا مَاءٌ غَدِيرٌ: (Lh:) or a place in which rain-water stagnates, whether small or large, not remaining until the summer: (Lth:) or a river: (Msb:) [but this is extr.:] plural [of pauc. أَغْدِرَةٌ, (occurring in a verse cited voce إِلَّا, &c.,) and of mult.] غُدْرَانٌ (S, Msb, K, TA) and غُدُرٌ (S, Nh, L, TA,) which last is sometimes contracted into غُدْرٌ: (TA:) in the K, the last plural is said to be of the measure of صُرَدٌ; [i. e.
غُدَرٌ;] but this is inconsistent with what is said in other lexicons, as shown above: and it is also said in the K that غُدَرٌ signifies the same as غَدِيرٌ, in the sense first given above; but it appears that this is a plural of غُدْرَةٌ; and that, in the K, we should read, for وَالغَدِيرُ, كَالغَدِيرِ, and place this before, instead of after, its explanation. (TA.)
