Core sense — unclean, dirty, or impure; a man having an incurable diseasegenerated
1figurative · مجازunclean, dirty, or impure—نَجَسٌ
unclean, dirty, or impure—نَجُسٌ
unclean, dirty, or impure—نَجْسٌ
unclean, dirty, or impure—نِجْسٌ
This form is a maṣdar used as an adjective, and so serves as singular, dual and plural, masculine and feminine, without change.
This last form is used only when the word is preceded or followed by رِجْسٌ, or only when it is preceded by رِجْسٌ (Fr, S, and Har in the Durrat-el-Ghowwás); but that remark holds correctly only for most instances.
The headword form and the last of these five are also used as plurals; when so used, قَوْمٌ or some other ism jamʿ is probably understood.
The plural of every one of the other forms is أَنْجَاسٌ, and of the fourth and fifth of the five forms, and perhaps of the first and third also, نِجْسَةٌ, though I do not remember similar instances. [See also نَجَاسَةٌ below.]
unclean, said of a man—نَجِسٌ
unclean, said of a man—نَجْسٌ
men are of several kinds, and most of them are unclean—النَّاسُ أَجْنَاسٌ وَأَكْثَرُهُمْ أَنْجَاسٌ

Applied to a man, both properly and figuratively.
The two following examples are said in the A to be figurative.

All the forms above also mean: a man having an incurable disease.
