O-PIN-ING, ppr.

Thinking. [Obs.]

O-PIN'ION, n. [opin'yon; Fr. id.; L. opinio, from opinor, to think, Gr. επινοεω; or أبَنَ abana, to think, to suspect. The primary sense is to set, to fix in the mind, as in L. suppono.]

  1. The judgment which the mind forms of any proposition, statement, theory or event, the truth or falsehood of which is supported by a degree of evidence that renders it probable, but does not produce absolute knowledge or certainty. It has been a received opinion that all matter is comprised in four elements. This opinion is proved by many discoveries to be false. From circumstances we form opinions respecting future events. Opinion is when the assent of the understanding is so far gained by evidence of probability, that it rather inclines to one persuasion than to another, yet not without a mixture of uncertainty or doubting. Hale.
  2. The judgment or sentiments which the mind forms of persons or their qualities. We speak of a good opinion, a favorable opinion, a bad opinion, a private opinion, and public or general opinion, &c. Friendship gives a man a peculiar right and claim to the good opinion of his friend. South.
  3. Settled judgment or persuasion; as, religious opinions; political opinion.
  4. Favorable judgment; estimation. In actions of arms, small matters are of great moment, especially when they serve to raise an opinion of commanders. Hayward. However, I have no opinion of these things. Bacon.

It is brought in cakes or masses weighing from eight ounces to a pound. It is heavy, of a dense texture, of a brownish yellow color, not perfectly dry, but easily receiving an impression from the finger; it has a faint smell, and its taste is bitter and acrid.
