[أَعْرَقُ is also a comparative and superlative epithet signifying More, and most, rooted in a quality or faculty: regularly formed from عَرُقَ, or irregularly from أُعْرِقَ: but perhaps post-classical. (See De Sacy's “ Anthol. Gram. Arabe, ” p. 183, lines 1 and 3, of the Ar. text; and p. 441 of the Notes, in which he has expressed his opinion that it signifies “ qui a jeté de plus profondes racines. ”)]
