Full Definition
الأَرْبِعَآءُ
, [also written without tenween when not rendered determinate by the article or otherwise accord. to most authorities, who make it fem., but with tenween when indeterminate accord. to those who make it masc.,] and الأَرْبَعَآءُ, the latter on the authority of some of the BenooAsad, and الأَرْبُعَآءُ, which is a form of the word seldom used, and الإِرْبِعَآءُ, and الإِرْبَعَآءُ, the last two mentioned by IHsh, the first of all the most chaste, but it is the only sing. word of its measure, except أَرْمِدَآءُ, the name of A certain day; [namely Wednesday;] the fourth day of the week; as also
; but this is post-classical: the dual of أَرْبِعَآء is أَرْبِعَاوَانِ; and the pl. is أَرْبِعَاوَاتٌ, [accord. to those who make the sing. fem.;] or the dual is أَرْبِعَآءَانِ, and the pl. is أَرْبِعَآءَاتٌ; thus says Aboo-Jukhádib, regarding the noun as masc.: Aboo-Ziyád used to say, مَضَى الأَرْبِعَآءُ بِمَا فِيهِ [Wednesday passed with what in it], making it sing. and masc. [because he meant thereby يَوْمُ
الأَرْبِعَآءُ]; but Abu-l-Jarráh used to say, مَضَتِ
الأَرْبِعَآءُ بِمَا فِيهِنَّ, making it fem. and pl., and employing it like a n. of number: Th is related to have mentioned أَرَابِيعُ as a pl. of الأَرْبِعَآءُ; but ISd says, I am not sure of this. The word has no dim. (Sb, S in art. امس.)
