أَعْلَمُ
1.
[More, and most, knowing or learned]. Applied to God, [it may often be rendered Supreme in knowledge: or omniscient: but often, in this case,] it means [simply]
عَالِمٌ [in the sense of knowing, or cognizant]. (Jel in iii. 31, and I'Ak p. 240.) [Therefore اَللّٰهُ أَعْلَمُ virtually means, sometimes, God knows best; or knows all things: and sometimes, simply, God knows.]
2.
Also [Harelipped; i. e.] having a fissure in his upper lip: (S, Mgh, Msb, K:) or in one of its two sides: (K:) the camel is said to be اعلم because of the fissure in his upper lip: when the fissure is in the lower lip, the epithet أَفْلَحُ is used: and أَشْرَمُ is used in both of these, and also in other, similar, senses: (TA:) the feminine of أَعْلَمُ is عَلْمَاءُ: (S, Msb, TA:) which is likewise applied to a lip (شَفَةٌ). (TA.)
3.
العَلْمَاءُ signifies also The coat of mail: (K:) mentioned by Sh, in the book entitled كِتَابُ السِّلَاحِ; but as not heard by him except in a verse of Zuheyr Ibn-Khabbáb [?]. (TA.)
