مُسْتَدِيرٌ

[Having, or assuming, a round, or circular, form; round, or circular: see also مُدَوَّرٌ]. You say قَمَرٌ مُسْتَدِيرٌ مُسْتَنِيرٌ [A round, or full, shining moon]. (A. [Accord. to the TA, the latter epithet is added as an explicative of the former; but this I think an evident mistake.])
