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

And عَيْشٌ رَاتِبٌ Constant, or continual, (M, TA,) fixed, settled, or established, (TA,) means of subsistence. (M, TA.) 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.) b2:  [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.]تُرْتَبٌ and تُرْتُبٌ and تَرْتُبٌ: see the next preceding paragraph, in four places. b2:  You say also, جَاؤُوا تُرْتَبًا and تُرْتُبًا, meaning They came all together.

[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.) A2:  Also the second of these three words, (T in art. ترب, and M, and L,) or the first of them, (K,) A bad slave: (T, K:) 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.

(K.) أَخَذَ فُلَانٌ تُرْتُبَّةً Such a one took what was like a road, to tread it.

(A.) b3:  The pl. also signifies Narrow and rugged parts of valleys. (TA from a trad.) b4:  And the sing., Any difficult station or position. (M.) b5:  See also رَتَبٌ, in two places. b6:  [In post-classical works, and in the language of the present day, it is applied to A mattress, upon which to sit or recline or lie; such as is spread upon a couch-frame or upon the ground.]
