Pronunciation

Etymology

It is inherited from Middle English opinioun,[2] borrowed from Old French opinion (“what one thinks, supposition, judgment, belief”),[3][2] and directly borrowed from Latin opīniō (“opinion, conjecture, belief; esteem”),[2][3] from the stem of opīnor (“I think, judge, suppose”),[2][4] the source of opine.[3][4] Etymonline takes it to Proto-Indo-European *op- (“to choose”), the root of option.[2]

Earliest recorded meaning

A judgment or conclusion, especially one not resting on certain knowledge: before 1325, in Cursor Mundi,[3] the early 14th century;[2] the OED has an opinion on a particular point from before 1300.[5]

Semantic evolution

The word has always tended toward a judgment influenced more by feeling than by reason.[2] The estimate one forms of a person or thing is from about 1375[5] or about 1500,[2] and the formal statement of an expert or a judge from about 1470.[5][2] The general view held by a community, public opinion, is by 1735,[2] although opinion qualified as common or general is from about 1425.[5] To be of opinion is from 1485.[5] Johnson (1755) defined it as “persuasion of the mind, without proof or certain knowledge”.[6] Opinionated is from 1601, from an earlier opinionate.[3][4] Opinion poll is a 20th-century compound.[1]
