A.P. Buddhadatta Mahathera, Concise Pali-English and English-Pali Dictionary [available as digital version from Metta Net, Sri Lanka]

Onīta [in form = Sk. avanīta, but semantically = apanīta. Thus also BSk. apanīta, pp. of apa + nī, see apaneti] only found in one ster. phrase, viz. onīta -- patta -- pāṇi "having removed (or removing) his hand from the bowl", a phrase causing constructional difficulties & sometimes taken in glosses as "onitta˚" (fr. nij), i. e. having washed (bowl and hands after the meal). The Cs. expln. as onīto pattato pāṇi yeva, i. e. "the hand is taken away from the bowl". The spelling is frequently oṇīta, probably through BB sources. See on term also Trenckner, Notes 6624 & cp. apa -- nīta -- pātra at M Vastu iii.142. The expression is always combd. with bhuttāvin "having eaten" and occurs very frequently, e. g. at Vin ii.147: D i.109 (= DA i. 277, q. v. for the 2 explns. mentioned above M ii.50, 93; S v.384; A ii.63; Sn p. 111 (= pattato onītapāṇi, apanītahattha SnA 456); VvA 118; PvA 278.
