Nibbuta represents Sk. nirvṛta (e.g. Avs.i.48) as well as nivṛta, both pp. of vṛ; which in itself combines two meanings, as exhibited in cognate languages and in Sk. itself: (a) Idg. ṷer to cover, cover up (Lat. aperio = *apa-veri̯o to cover up, Sk. varutram upper garment, “cover”) and (b) *ṷel to resolve, roll move (Lat. volvo = revolve; Gr. ε ̔́λις, ἐλύω; Sk. vāṇa reed = Lat. ulva; Sk. ūrmi wave; P. valli creeper, valita wrinkled). *ṷer is represented in P. by e.g. vivarati to open, nivāreti to cover, obstruct, nīvaraṇa, nivāraṇa obstruction; *ṷel by āvuta, khandh-āvāra, parivāra vyāvaṭa (busy with = moving about), samparivāreti Thus we gain the two meanings combined and used promiscuously in the one word because of their semantic affinity: (a) *nivṛta covered up, extinguished, quenched and (b) *nirvṛta without movement, with motion finished (cp. niṭṭhita), ceasing, exhaustion, both represented by P. nibbuta
■ In derivations we have besides the rootform vṛ; (= P. bbu˚) that with guṇa vṝ (cp. Sk. vārayati vrāyati) or vrā = P.* bbā˚ (with which also cp. paṭivāṇa = *prativāraṇa). The former is in nibbuti (ceasing, extinction, with meaning partly influenced by nibbuṭṭhi = Sk. nirvṛṣṭi pouring of water), the latter in instr. nibbāti and nibbāyati (to cease or to go out) and trs. nibbāpeti (Caus.: to make cease, to stop or cool and further in nibbāna (nt. instr. abstr.) (the dying out)
