جُمْجُمَةٌ

The skull; i. e. the bone that contains the brain: (S, Msb, K: *) or i. q. قِحْفٌ [i. e. the bone above the brain, or a separate portion of the skull, or a distinct bone of the skull]: (K:) or the bones of the head; (IAar, Mgh, TA;) all of them; the uppermost of them being the هَامَة; (IAar, TA;) or the هامة is the جمجمة altogether; (ISh, TA;) and the قحف is said to be a piece of the جمجمة: (TA:) plural جُمْجُمٌ, (K,) [or this (in the CK, erroneously, جَمْجَمٌ) is a coll. gen. n.,] and جَمَاجِمُ [is the plural properly so called, and that which is more commonly known]. (TA.)

Sometimes it is used to signify A man; so that one says, خُذُوا مِنْ كُلِّ جُمْجُمَةٍ دِرْهَمًا [Take ye from every man, or head, a dirhem]; like as one says, مِنْ كُلِّ رَأْسٍ: (Msb:) and وَضَعَ الإِمَامُ الخَرَاجَ عَلَى الجَمَاجِمِ عَلَى كُلِّ جُمْجُمَةٍ كَذَا [The Imám imposed the tax, or land-tax, upon the heads; upon every head so much]. (Mgh.)

A wooden bowl: (S, K:) a bowl of glass; as also قِحْفٌ. (Az, TA.)

A kind of measure for corn or the like. (K.)

Also (assumed tropical:) Chiefs, or lords, of the Arabs; because the جمجمة is the head, which is the most noble of the members: (TA:) also, (TA,) [the plural] جَمَاجِمُ has this meaning. (T, K, TA.) And (assumed tropical:) Any sons of a father that are persons of might, or power, and eminence, or nobility: (T, TA:) and [the plural] جَمَاجِمُ the tribes (قَبَايءِل) of the Arabs which comprise بُطُون, and in relation to which persons are called; as Kelb Ibn-Webreh; for when you say كَلْبِىٌّ, you do not need to call the person in relation to any of the بطون: (S:) or the tribes (قبايءل) in relation to which the بطون are called; as also جِمَامٌ. (K.)

A well that is dug in salt ground. (S, K.)

Sixty head of camels. (IF, IB, TA.)

جَمَاجِمُ الحَارِثِ The piece of wood at the head of which is the ploughshare. (TA.)
