كر

مُكَرَّرٌ ذ [ Repeated; reiterated ]. ― -b2- المُكَرَّرُ The letter ر: (K:) because of the faltering of the tip of the tongue which is observable when one pauses after uttering it, occasioned by the reiteration with which that is done; wherefore, with respect to اـِمَالَة, [as an obstacle thereto,] it is reckoned as two letters. (TA.) ― -b3- [مُكَرَّرٌ, in the present day, also signifies Refined, as an epithet applied to sugar, &c.]
