Dictionary Arabic-English Lexicon by Edward William Lane (d. 1876)
Entry سرمد
سَرْمَدٌ [signifies, or implies,] Continuance, or incessant continuance, (دَوَام, Kh, M, L, and اِتِّصَال, Kh, L,) of time, (Kh, M, L,) either of night or of day. (Kh, L.) [I have said “ or implies ” because I have not found it used otherwise than as an epithet, in the following senses.]
Continuing; or continuing incessantly, or endlessly; syn. دَائِمٌ; (Zj, S, L, K;) or دَائِمٌ لَا يَنْقَطِعُ. (Nh, L.) It is applied in this sense to night (Nh, L) [and also to day: to each in the Kur xxviii. 71 and 72]: and to night as meaning Long. (L, K.)
Accord. to El-Fakhr Er-Rázee, it is derived from السَّرْدُ, which denotes consecutiveness and uninterruptedness, and the م is added to give intensiveness to the signification: if so, its proper place is in art. سرد; its measure being فَعْمَلٌ: (MF:) [thus] its م is augmentative like the م in دُلَامِصٌ. (Bd in xxviii. 71.)
One says also, هُوَ لَكَ سَرْمَدًا He, or it, is thine ever, or for ever. (Mgh in art. سمد.) سَرْمَدِىٌّ Having neither beginning nor end. (KT.)
E.W. Lane's Arabic-English Lexicon (8 parts, London, 1863-93) is a major Arabic-English dictionary based on 112 sources, mostly medieval ones, along with al-Zabidi's Taj al-Aroos (also included in Lisaan.net). Lane died before he could finish the work, his great-nephew Stanley Lane-Poole finished it, publishing Volumes VI, VII and VIII from 1877–1893 using Lane's incomplete notes. Lane-Pool's work is of lower quality than Lane's. The work of Reinhart Dozy (see below) was meant as a supplement to Lane's work that covers modern Arabic (Lane focused on classical Arabic only).
