عُنْصُرٌ ذ (S, O, Msb, K) and عُنْصَرٌ, (S, O, K,) the former of which is the more commonly known, but the latter [accord. to my copy of the Msb عَنْصر, but this I regard as a mistake of the copyist,] is the more chaste, (TA,) Origin; syn. أَصْلٌ: (S, O, Msb, K:) race, lineage, or family: (Msb:) rank or quality, nobility or eminence, reputation or note or consideration, derived from ancestors, or from one's own deeds or qualities; syn. حَسَبٌ: (S, O, K:) pl. عَنَاصِرُ. (Msb.) You say فُلَانٌ كَرِيمُ العُنْصُرِ [ Such a one is of generous origin, or race, &c.,] like as you say كَرِيمُ العَصِيرِ. (L.) ― -b2- An element (أَصْلٌ) [ of those ] whereof are composed the material substances of different natures; [ an element considered as that from which composition commences: ] it is of four kinds; namely, fire, air, earth, and water. (KT.) [But this application belongs to the conventional language of philosophy. See also مَادَّةٌ, and جِسْمٌ.]
