دعمص

دُعَيْمِيصٌ 1 [dim. of دُعْمُوصٌ]. ― -b2- One says, هُوَ دُعَيْمِيصُ هٰذَا الأَمْرِ, meaning He is acquainted with, or knowing in, this affair. (S, K.) دُعَيْمِيصُ الرَّمْلِ was the name of a certain cunning, or knowing, or skilful, man; and hence the saying above mentioned: (S:) he was a black slave, very cunning or knowing or skilful, and an expert guide of the way. (K.) And [hence] one says, أَهْدَى مِنْ دُعَيْمِيصُ الرَّمْلِ [ More expert in showing the way than Do'eymees-er-Raml ]. (O, TA.)
