برجمبُرْجُمَةٌ (in the Ham p. 352 بُرْجُمٌ) is the sing. of بَرَاجِمُ (S, Mgh, Msb, K) and بُرْجُمَاتٌ; (T, TA;) and signifies [A knuckle, or finger-joint;] the outer, or the inner, joint, or place of division, of the fingers: and (as some say, TA) the middle toe of any bird: (K:) or بَرَاجِمُ signifies all the finger-joints; (A'Obeyd, K;) as also رَوَاجِمُ [a mistranscription for رَوَاجِب]: (A'Obeyd, TA:) or the parts of the fingers that are protuberant when one clinches his hand: (Ham ubi suprà:) or the backs of the finger-bones: (K:) or the finger-joints (S, Mgh) that are between the أَشَاجِع and the رَوَاجِب; (S;) i. e. (S, Mgh) [the middle knuckles; (see أَشْجَعُ and رَاجِبَةٌ;)] the heads of the سُلَامَيَات, (S, Mgh, Msb, K,) on the back, or outer side, of the hand, (S, Msb,) which become protuberant when one clinches his hand: (S, Mgh, Msb, K:) or, as in the Kf, the heads of the سلاميات; and their inner and outer sides are termed the رَوَاجِب: (Msb:) accord. to the T, the wrinkled parts at the joints of the fingers; the smooth portion between which is called رَاجِبَةٌ: or, as in another place, in the backs of the fingers; the parts between them being called the رَوَاجِب: in every finger are three بُرْجُمَات, except the thumb: or, as in another place, in every finger are two of what are thus termed: it is also explained as signifying the joints in the backs of the fingers, upon which the dirt collects. (TA.) The phrase الأَخْذُ بِالبَرَاجِمِ, meaning The seizing with the hand, is one requiring consideration [as of doubtful character]. (Mgh.) [See also بُرْثُنٌ.]
