كثب

كَثَبٌ ذ Nearness [ with respect to place ]. (S, K.) The ب in this word is sometimes changed into م. (Msb.) هُوَ كَشَبَكَ He is near thee. Sb says that it is not used otherwise than as an adverbial noun of place. But you say, هُوَ يَرْمِى مِنْ كَثَبٍ He shoots, or throws, from a near spot, and from a distance from which he can reach, or hit. (TA.)
