(TA.) You say أَمْرٌ رَاتِبٌ A thing, or an affair, continual, or uninterrupted, (دَارٌّ.) constant, firm, steady,, &c.: andأَمْرٌ تُرْتَبٌ↓, the latter word of the measure تُفْعَلٌ, with damm to the ت and fet-ḥ to the ع, a thing, or an affair, constant, firm, steady,, &c.

And مَا زِلْتُ عَلَى هٰذَا رَاتِبًا I ceased not to be, or to do, thus constantly; as also رَاتِمًا; in which, IJ says, the م is app. a substitute for ب, because we have not heard رَتَمَ used like رَتَبَ; but it may be radical, from الرَّتِيمَةُ. (M.)

[رَاتِبٌ in the modern language, used as a subst., signifies A set pension, salary, and allowance; a ration; and any set office, or task: and so رَاتِبَةٌ; pl. رَوَاتِبُ.]

i. e. [And it was a just claim that we had upon the people,] settled, or established. (TA.) The first ت in تُرْتَبٌ is augmentative, because there is no word like جُعْفَرٌ; and the derivation also is an evidence of this, for the word is from الشَّىْءُ الرَّاتِبُ. (M.)

Also the second of these three words, (T in art. ترب, and M, and L,) or the first of them, (Ḳ,) A bad slave: (T, Ḳ:) or a slave whom three persons inherit, one after another; because of his continuance in slavery: [it being a common custom for a man to make a good slave free at his death:] mentioned by Th.
