مُغَارٌّ

(S, K) and مُغَارَّةٌ (TA) A she-camel having little milk: (S, K:) or having lost her milk by reason of some accident or disease; as some say, on disliking her young one, and rejecting the milker: (TA:) or taking fright, and drawing up her milk, (ISk, S,) after yielding it freely: (TA:) plural مَغَارُّ, (S, K,) imperfectly decl. [being originally مَغَارِرُ]. (S.)

Hence, (TA,) (tropical:) A niggardly, or tenacious, hand: (K:) but according to the A and the TS, you say رَجُلٌ مُغَارُّ الكَفِّ, meaning a niggardly, or tenacious, man. (TA.)
