O. O
O Initial o in Pali may represent a Vedic o or a Vedic au (see ojas, ogha, etc.). Or it may be gu*a of u (see
o)!rika, opakammika, etc.). But it is usually a prefix representing Vedic ava. The form in o is the regular
use in old Pali; there are only two or three cases where ava, for metrical or other reasons, introduced. In
post -- canonical Pali the form in ava is the regular one. For new formations we believe there is no
exception to this rule. But the old form in o has in a few cases, survived. Though o; standing alone, is
derived from ava, yet compounds with o are almost invariably older than the corresponding compounds
with ava (see note on ogamana).
Oka
Oka (nt.) [Vedic okas (nt.), fr. uc to like, thus orig. "comfort", hence place of comfort, sheltered place,
habitation. The indigenous interpretation connects oka partly with ok!sa = fig. room (for rising), chance,
occasion (thus Nd1 487 on Sn 966: see anoka; SnA 573 ibid.; SnA 547: see anoka; SnA 573 ibid.; SnA
547: see below), partly with udaka (as contraction): see below on Dh 34. Geiger (P. Gr. § 20) considers oka
to be a direct contraction of udaka (via *udaka, *utka, *ukka, *okka). The customary synomym for oka
(both lit. & fig.) is !laya] resting place, shelter, resort; house, dwelling; fig. (this meaning according to later
commentators prevailing in anoka, liking, fondness, attachment to (worldly things) S iii.9 = Sn 844 (okam
pah!ya; oka here is expld. at SnA 547 by r(pa -- vatth! !di -- viñña*ass! ok!so); S v.24 = A v. 232 = Dh
87 (ok! anokam !gamma); Dh 34 (oka -- m -- okata ubbhato, i. e. oka -- m -- okato from this & that abode,
from all places, thus taken as okato, whereas Bdhgh. takes it as okasya okato and interprets the first oka as
contracted form of udaka, water, which happens to fit in with the sense required at this passage, but is not
warranted otherwise except by Bdhgh's quotation "okapu**ehi c"vareh" ti ettha udaka'". This quot. is taken
from Vin i.253, which must be regarded as a corrupt passage cp. remarks of Bdhgh. on p. 387: oghapu**eh"
ti pi p!&ho. The rest of his interpretation at DhA i.289 runs: "oka' oka' pah!ya aniketa -- s!r" ti ettha !layo,
idha (i. e. at Dh 34) ubhayam pi labbhati okamokato udaka -- sankh!t! !lay! ti attho", i. e. from the water's
abode. Bdhgh's expln. is of course problematic); Dh 91 (okam oka' jahanti "they leave whatever shelter
they have", expld. by !laya DhA ii.170). -- cara (f. ˚carik! J vi.416; ˚c!rik! M i.117) living in the house
(said of animals), i. e. tame (cp. same etym. of "tame" = Lat. domus, domesticus). The passage M i. 117,
118 has caused confusion by oka being taken as "water". But from the context as well as from C. on J
vi.416 it is clear that here a tame animal is meant by means of which other wild ones are caught. The
passage at M i.117 runs "odaheyya okacara' &hapeyya okac!rika'" i. e. he puts down a male decoy and
places a female (to entice the others), opp. "(haneyya o. n!seyya o." i. e. takes away the male & kills the
female. -- (ñ)jaha giving up the house (and its comfort), renouncing (the world), giving up attachment Sn
1101 (= !laya'jaha' SnA 598; cp. Nd2 176 with v. l. ogha'jaha). -- anoka houseless, homeless,
comfortless, renouncing, free from attachment: see separately.
