عُنَانَاكَ

means The utmost of thy power, or ability, or of thy case: (S, K:) so in the saying, عُنَانَاكَ أَنْ تَفْعَلَ كَذَا [The utmost of thy power, &c., is, or will be, thy doing such a thing]: (S:) as though from ↓ المُعَانَّةُ; (S, TA;) the case being that thou desirest to do a thing, and an obstacle intervenes in the way to it, preventing thee and withholding thee from it: (TA:) but it is disputed whether it be correctly thus, or غُنَامَاكَ. (IB, TA.)
