جَامٌ A vessel, (Ḳ,) or فَاثُور [i. e. a basin, or a table, or a tray used as a table], (IAạr, TA,) of silver: (IAạr, Ḳ, TA:) or a white dish or tray, of glass or of silver: (Mgh:) or a vessel (ظَرْف) of glass: (Ḥar p. 200:) [a Persian word, i. e. جَامْ, arabicized; or] a genuine Arabic word: (TA:) pl. [of pauc.] أَجْؤُمٌ, with ء, (IAạr, Ḳ,) and أَجْوَامٌ, and (as some say, IAạr, TA, [of mult.,]) جُومٌ, (Ḳ,) with damm, (TA, in the CK جَوْمٌ,) and [of pauc. or mult.] جَامَاتٌ: (IAạr, Ḳ:) but IB says that جَامٌ is pl. ofجَامَةٌ↓, as is also جَامَاتٌ: [instead of which he should rather have said that جام is a coll. gen. n. of which the n. un. is جامة, (though this requires consideration, as the former is commonly used as a sing.,) and that the pl. of the latter is جامات:] that its dim. is جُوَيْمَةٌ↓: and that it, i. e. جام, is of the fem. gender.
