O-CEAN, a. [o'shun.]

Pertaining to the main or great sea; as, the ocean wave; ocean stream. Milton.

O'CEAN, n. [o'shun; L. oceanus; Gr. ωκεανος; Fr. ocean; Ir. ocein, aigein; W. eigiawn, aig or eigion. In Welsh, the word is rendered a great source, the middle, the abyss or great deep, and is allied in orthography to eigian, force, or a forcing out, a producing; eigiaw, to bring forth, from aig, what brings forth, the female, the womb, the sea, a shoal of fishes, a flock, or herd. Bochart cites many authorities to prove that the ancients understood the ocean to encompass the earth, and he supposes it to be derived from the Heb. Ch. and Syr. חוג hog, to encompass, whence a circle. This is probably an error. The word seems to have for its origin greatness or extent.]
