دُرْدُرٌ

The part of the gums where the teeth grow: (TA:) or the part where the teeth grow of a child: (S, K, TA:) or the part where the teeth grow both before they grow and after they have fallen out: (K, TA:) plural دَرَادِرُ. (S.) Hence the prov., أَعْيَيْتِنِى بِأُشُرٍ فَكَيْفَ بِدُرْدُرٍ, (S, K,) or فَكَيْفَ أَرْجُوكَ بِدُرْدُرٍ, (TA,) i. e. Thou [weariedst me, and] didst not accept good advice when thou wast a young woman and when thy teeth were serrated and sharp in their extremities; then how should I hope for any good in thee now when thou hast grown old, and the places of the growth of thy teeth have become apparent by reason of age? (K, * TA.) In the K we read لَمْ تَقْبِلَ النُّصْحَ شَابًّا: but it should be لَمْ تَقْبَلِى النُّصْحَ شَابَّةً. (TA.) دُرْدُرٌ is also said to signify The extremity, or tip, of the tongue: or, as some say, its root: but the signification commonly known is that first given above. (TA.)
