(TA.) ― -b2- 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 الاـِمَامُ الخَرَاجَ عَلَى الجَمَاجِمِ عَلَى كُلِّ جُمْجُمَةٍ كَذَا [ The Imám imposed the tax, or land-tax, upon the heads; upon every head so much ]. (Mgh.) ― -b3- A wooden bowl: (S, K:) a bowl of glass; as also قِحْفٌ. (Az, TA.) ― -b4- A kind of measure for corn or the like. (K.) ― -b5- 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 pl.] 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 pl.] جَمَاجِمُ the tribes (قَبَائِل) 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 (قبائل) in relation to which the بطون are called; as also ↓ جِمَامٌ. (K.) -A2- A well that is dug in salt ground. (S, K.) -A3- Sixty head of camels. (IF, IB, TA.) -A4- جَمَاجِمُ الحَارِثِ The piece of wood at the head of which is the ploughshare. (TA.)
