رَجَمٌ

Stones (Msb, TA) that are placed upon a grave. (TA.)

And hence, (Msb, TA,) A grave; (S, Msb, K, TA;) because stones are collected together upon it; (Msb;) as also ↓ رَجْمَةٌ and ↓ رُجْمَةٌ: (K:) the plural of رَجَمٌ is أَرجَامٌ: you say, هٰذِهِ أَرْجَامُ عَادٍ These are the graves of [the tribe of] 'Ád: (TA:) and ↓ رُجْمَةٌ, of which the plural is رُجَمٌ and رِجَامٌ, signifies also, like as does ↓ رُجُمٌ, stones, (K,) or high stones, (TA,) that are set up upon a grave: (K, TA:) or both these signify a sign [that is set up upon a grave; or a tombstone: see 2] : (K:) or the former of them (رُجْمَةٌ) signifies stones collected together, (Lth, Msb, TA,) as though they were the graves of [the tribe of] 'Ád; (Lth, TA;) and its plural is رِجَامٌ: (Msb:) or it is singular of رُجَمٌ and رِجَامٌ which signify large stones, less then [such as are termed] رِضَام, (S,) or like رِضَام, (TA,) sometimes collected together upon a grave to form a gibbous covering to it. (S.)

Also (i. e. رَجَمٌ) A well. (K.)

And A [kind of oven such as is called] تَنُّور [q. v.]. (K.)

And i. q. جُفْرَةٌ, with جيم, according to the K, i. e. A round space in the ground: or, as in other lexicons, حُفْرَةٌ [meaning a hollow, or cavity, in the ground, made by digging, or natural]. (TA.)

-A2- Also Brothers, or brethren: [a quasipl. n.:] singular, according to Kr, ↓ رَجْمٌ and رَجَمٌ; [so that the latter is used as a singular and as a plural;] but (ISd says, TA) I know not how this is. (K, TA.) [See also رَجْمٌ.]
