عِصَامٌ ذ The tie of a قِرْبَة [or water-skin]; (S, Msb;) [i. e.] its [ tie called ] وَكَاآء [ which is bound round the head to confine the contents ]: (TA:) and the strap that is used for the carrying thereof: (S, Msb:) or a cord that is used for the tying, or binding, of the leathern bucket and of the water-skin and of the [leathern vessel for water called] اـِدَاوَة: and the loop-shaped handle that serves for the suspending of the [bag, or other receptacle, for travelling-provisions or for goods or utensils &c. called] وِعَاآء: (K:) and anything that serves for the protection, or preservation, of a thing: (TA:) pl. [of pauc.] أَعْصِمَةٌ and [of mult.] عُصْمٌ, (K, TA,) or عُصُمٌ, (Msb, and so in some copies of the K,) and عِصَامٌ, like the sing., of the class of دِلَاصٌ: (AZ, K:) but Az states, as what had been heard [app. by him] from the Arabs, respecting the عُصْم of [the leathern water-bags called] مَزَاد, that they are the cords that are fixed in the loops of the pairs of water-bags, and with which they are tied when they are bound upon the back of the camel; after which the [ rope called ] رِوَاآء is bound over them: they are erroneously said by Lth to be the طَرَائِق [app. meaning borders ] of the extremity of the مَزَادَة [or leathern water-bag ], at the place of the كُلْيَة [or kidney-shaped piece of leather to which a loop is sewed ]. (TA. [See also خُصْمٌ.]) Mention is made, in a trad., of a place where a camel was shackled with عُصْم, as meaning that its abundance of herbage confined him so that he would not go away in search of pasturage. (TA.) ― -b2- Also The cord, or bond, of the [vehicle called] مَحْمِل, (K, * TA,) which is bound at the extremity of [ each of the transverse pieces of wood called ] the عَارِضَانِ [correctly عَارِضَتَانِ], in the upper part of each of these: [for,] as Lth says, there are two of such cords, or bonds: and Az says that the عِصَامَانِ of the مَحْمِل are like those of the [ pair of leathern water-bags called ] مَزَادَتَانِ. (TA.) ― -b3- And The slender part of the end of the tail; (M, K;) and عِضَامٌ is a dial. var. thereof: (TA: [but see the latter:]) or the tail with its hair and its عَسِيب [q. v.]: (ISh, TA:) pl. أَعْصِمَةٌ. (K.) ― -b4- See also عُصْمَةٌ, in two places. ― -b5- Also Collyrium: (K, TA:) mentioned on the authority of El-Muärrij: so called because it defends and strengthens the eye. (TA.)
