رُبَاعُ
Root: ربع
Full Definition
رُبَاعُ
[Four and four: four and four together: or four at a time and four at a time:] is a deviation from the original form, or أَرْبَعَةٌ أَرْبَعَةٌ; for which reason, [and, accord. to general opinion, because it is at the same time an epithet, (see ثُلَاثُ,)] it is imperfectly decl.: but the dim. is
رُبَيِّعٌ , perfectly decl. (S voce ثُلَاثُ, q. v.) [See exs. voce ثُلَاثُ.] In the Kur iv. 3, El-Aamash read
instead of وَرُبَاعَ.
