OP'PI-LA-TIVE, a. [Fr. oppilatif.]

Obstructive. Sherwood.

OP-PLE'TED, a. [L. oppletus.]

OP-PO'NEN-CY, n. [See Opponent.]

The opening of an academical disputation; the proposition of objections to a tenet; an exercise for a degree. [I believe not used in America.] Todd.

OP-PO'NENT, a. [L. opponens, oppono; ob and pono, to set, put or lay, that is, to thrust against; Heb. Syr. Ch. and Ar. בנה, to build, that is, to set, to found, L. fundo.]

That opposes; opposite; adverse. Prior.


One that opposes; particularly, one that opposes in controversy, disputation or argument. It is sometimes applied to the person that begins a dispute by raising objections to a tenet or doctrine, and is correlative to defendant or respondent. In common usage, however, it is applicable to either party in a controversy, denoting any person who opposes another or his cause. Opponent may sometimes be used for adversary, and for antagonist, but not with strict propriety, as the word does not necessarily imply enmity nor bodily strife. Nor is it well used in the sense of rival or competitor.

OP-POR-TUNE, a. [L. opportunus; ob and porto, to bear or bring; probably from the root of fero or porto, to bear. The sense of the verb opporto, would be to bring to or upon. See Import, Importune. In this and all words of like signification, the primary sense is to fall, come or bring to. See Luck, Fortune, Season.]

Properly, having come or being present at a proper time; hence, seasonable; timely; well timed. It agrees with seasonable rather than with convenient, though the sense of the latter may be included in it. Perhaps in view / Of those right confines, whence with neighboring arms, / And opportune excursion, we may chance / Re-enter heaven. Milton.


Seasonably; at a time favorable for the purpose. It has been applied to place, as well as to time, but its proper application is to time, and hence it accords with seasonably, rather than with conveniently.


In seasonable time.

OP-POR-TU'NITY, n. [L. opportunitas.]

  1. Fit or convenient time; a time favorable for the purpose; suitable time combined with other favorable circumstances. Suitableness of time is the predominant signification, but it includes generally circumstances of place and other conveniences adapted to the end desired. A wise man will make more opportunities than he finds. Bacon. I had an opportunity to see the cloud descend. Brown. Neglect no opportunity of doing good. Atterbury.
  2. Convenient means. I had an opportunity of sending the letter, or no opportunity to send it. Opportunities rarely occur or frequently offer.

  2. To object or act against in controversy. – Johnson.

OP-POSE, v.t. [s as z. Fr. opposer; ob and poser, to set; L. oppono, opposui. It is doubtful whether Fr. poser, and the preterit and participle passive of the Latin verb belong to pono. The change of n into s is unusual. Two different verbs may be used, as in L. fero, tuli. See Pose.]

  1. To set against; to put in opposition, with a view to counterbalance or countervail, and thus to hinder, defeat, destroy or prevent effect; as, to oppose one argument to another. I may without presumption oppose my single opinion to his. Locke.
