سَدٌّ

and ↓ سُدٌّ Any building, or construction, with which a place is closed or closed up, or stopped or stopped up: (M: [see also سِدَادٌ:]) a dam: (Msb:) a thing intervening, as a separation, a partition, a fence, a barrier, a rampart, or an obstacle, or obstruction, between two other things; (S, Msb, K:) and a mountain: (S, M, K: [in the last it seems that this meaning is restricted to the former word; but if restricted to either, it should be to the latter:]) or, as some say, anything that faces one, or is over against one, and bars, or excludes, (يَسُدُّ,) what is behind it: whence goats are said to be سَدٌّ يُرَى مِنْ وَرَايءِهِ الفَقْرُ (assumed tropical:) [a barrier behind which is seen poverty]; meaning that they are not of great utility: (M:) or سَدٌّ signifies what is made by man; and سُدٌّ, what is created by God, (Zj, M, Msb, K,) as a mountain: (Msb:) in the Qur'an, 18:92 and 93, and xxxvi. 8, some read with fet-h, and some with damm: (M, TA:) the plural is أَسْدَادٌ, [a plural of pauc.,] (A, Msb,) or أَسِدَّةٌ, [also a plural of pauc.,] and سُدُودٌ, [a plural of mult.,] the latter of these two agreeable with general analogy, and the former of them anomalous, or, [ISd says,] in my opinion, this (أَسِدَّةٌ) is plural of سِدَادٌ. (M.) You say, ضُرِبَ بَيْنَهُمَا سَدٌّ and سُدٌّ [A barrier, or an obstacle, was set between them two]: and ضُرِبَتْ بَيْنَهُمَا الأَسْدَادُ [Barriers, or obstacles, were set between them two]. (A.) And ضَرَبَتْ عَلَيْهِ الأَرْضُ بِالأَسْدَادِ (tropical:) [The earth, or land, set barriers, or obstacles, against him]; meaning, the ways became closed, or stopped, against him, and the courses that he should pursue became obscure to him: (K: in the CK ضُرِبَتْ:) the singular of أَسْدَادٌ [according to general analogy] is سُدٌّ. (TA.)

[Hence,] the former (سَدٌّ) also signifies, (Fr, S, M, L, K,) or ↓ سِدَادٌ, (A,) or the former and ↓ سَدَادَةٌ, (L,) (tropical:) A fault, or defect, (Fr, S, M, A, &c.,) such as blindness and deafness and dumbness, (S,) or such as closes, or stops, one's mouth, so that he does not speak: (A:) plural of the first, (S, M, K,) or of the second, (A,) أَسِدَّةٌ, [a plural of pauc.,] (S, M, A, K,) according to analogy سُدُودٌ, (S, M, K,) or أَسُدٌّ [which is a plural of pauc.]. (M.) You say, ↓ مَا بِهِ سِدَادٌ (tropical:) There is not in him any fault &c.: and فُلَانٌ بَرِىْءٌ مِنَ الأَسِدَّةِ (tropical:) Such a one is free from faults &c. (A.) And تَسُدُّ فَاهُ عَنِ الكَلَامِ ↓ مَا بِفُلَانٍ سَدَادَةٌ (assumed tropical:) There is not in such a one a fault that stops his mouth from speaking. (Aboo-Sa'eed, L.) And لَا تَجْعَلَنَّ بِجَنْبِكَ الأَسِدَّةَ (tropical:) By no means render thou thy bosom contracted so that thou shalt be unable to return an answer, like him who is deaf or dumb. (S, K.)

See also سُدٌّ.

سدّ [so in the TA, i. e. either سَدٌّ or سُدَّ,] also signifies (assumed tropical:) A she-camel by which the sportsman conceals himself from the game; also called دَرِيْيءَةٌند دَرِيعَةٌ whence the saying, رَمَاهُ فِى سدِّ نَاقَتِهِ (assumed tropical:) [He shot him, or shot at him, by his she-camel whereby he was concealing himself]. (IAar, TA.)

And سَدٌّ, (M,) or سُدٌّ, (O, K,) is also synonym with ظِلٌّ [as meaning (tropical:) Shade, or shadow; or cover, or protection]. (IAar, M, O, K, TA.) A poet cited by IAar says,

قَعَدْتُ لَهُ فِى سَدِّ نِقْضٍ مُعَوَّدٍ

لِذٰلِكَ فِى صَحْرَاءَ جِذْمٍ دَرِينُهَا

(tropical:) [I sat for him, i. e. lay in wait for him, in the shade, or cover, of a camel rendered lean by travel, accustomed to that, in a desert whereof the dry herbage was old]: i. e. I made him a cover, or screen, to me, in order that he might not see me: and by جِذْم he means “ old, ” because الجِذْمُ signifies الأَصْلُ, and there is nothing older than the أَصْل; and he uses it as an epithet because it implies the meaning of an epithet. (M.)

-A2- سَدٌّ also signifies A thing, (S, K,) [i. e.] a [basket such as is called] سَلَّة, (M, TA,) made of twigs, (S, M, K,) and having covers (أَطْبَاق): (S, K: [but this addition in the S and K seems properly to apply to the plural, as will be shown by what follows:]) plural سِدَادٌ and سُدُودٌ: (M, TA:) or, according to Lth, سُدُودٌ signifies [baskets such as are called] سِلَال, [plural of سَلَّةٌ,] made of twigs, and having covers (أَطْبَاق); one of which is called [not سَدٌّ but] ↓ سَدَّةٌ: and it is said also on other authority that the سَلَّة is called سَدَّةٌ and طَبْلٌ. (L, TA.)
