• O,
o,
the fourteenth letter of the Latin alphabet, corresponding to the
Gr. ο and
ω. The Latin language possessed both the sound and the sign from the earliest times; whereas the Etruscan language never possessed the
o, and the Umbrian seems not to have received it as an alphabetical character till a later period. The oldest monuments of the Latin tongue frequently employ
o where the classic language has
u. So on the Column. Rostr. MACESTRATOS (
acc. plur.), EXFOCIONT, CONSOL, PRIMOS (
nom. sing.), CAPTOM; in the epitaphs of the Scipios, HONC OINO, COSENTIONT, DVONORO OPTVMO VIRO (bonorum optumum virum); in the S. C. de Bacch. IN OQVOLTOD
al. And even in the later
inscrr. and
MSS., we sometimes find
o for
u:
POPLICO, POPOLVM, TABOLEIS, in the Tab. Bantina: FACIONDAM DEDERONT, Inscr. Orell. 1585:
MONDO, HOC TOMOLO, ib. 4858:
fondus, fornacatibus, solitodo, etc., in good MSS. (v. Freund, Cic. Mil. p. 18). And, on the contrary,
u for
o in the old forms, fruns, funtes, for frons, fontes,
v. h. vv.: RVBVSTIS for robustis, in the Cenot. Pisan.; v.
Inscr. Orell. 642:
NVMENCLATOR, Inscr. Grut. 630, 5:
CONSVBRINVS, ib. 1107, 1:
SACERDVS, ib. 34, 5:
VNV LOCV, ib. 840, 1.
O appears in
class. Lat. particularly in connection with
qu and
v: quom, avos. This interchange of
o and
u seems to have been effected rather by dialectical and local than by organic and historical causes; just as in the modern Italian dialects a preference is shown on the one hand for
o and on the other for
u, and in one and the same dialect the Latin
o has passed over into
u and the
u into
o. —On the commutation of
o and
e, see the letter E.—We have
o for
au in Clodius, plodo, plostrum, sodes,
etc. (also in polulum for paululum,
Cato, R. R. 10, 2).—
O inserted in the archaic forms:
Patricoles, Hercoles, v. Ritschl ap. Rhein. Mus. 8, p. 475 sq., and 9, p. 480. As an abbreviation, O. stands for omnis and optimus: I. O. M., Jovi Optimo Maximo: O. E. B. Q. C., ossa ejus bene quiescant condita, Inscr. Orell. 4489;
cf.:
O. I. B. Q., ossa illius bene quiescant, ib. 4483;
4490:
O. N. F., omnium nomine faciundae, ib. 4415:
O. T. B. Q., ossa tua bene quiescant: O. V., optimo viro, ib. 4135;
also: optimi viri, ib. 5037.
