دَلَمٌ

A certain thing resembling the serpent, found in El-Hijáz: (K:) or resembling what is termed the طَبُّوع; not a serpent: (TA:) or it signifies, (TA,) or thus ↓ دُلَمٌ, (so in the T according to the TT,) the young one of a serpent: and the plural is أَدْلَامٌ. (T, TA.) Hence the prov., هُوَ أَشَدُّ مِنَ الدَّلَمِ [He is more distressing than the دلم]: (K:) and one says also, هُوَ أَشَدُّ مِنَ الدَّلَمِ فِى الشَّفَةِ, meaning [He is more distressing] than flaccidity and pendulousness in the lip. (This, as well as the former saying, being mentioned in the TA, as from the K.)
