opinion

• n. 意見、主張

ラテン語のopinari（意見を述べる、意味を表す）から、PIE*op（選ぶ、区別する）に由来し、語源的にはoptionと同じ。

opinion

opinion: [13] Opinion comes via Old French from Latin opīniō, a derivative of opīnārī ‘think’. It is not certain where this came from, although some have linked it with Latin optāre ‘choose’, source of English adopt [16], co-opt [17], opt [19], and option [17].
=> adopt, opt, option

opinion (n.)

c. 1300, from Old French opinion "opinion, view, judgements founded upon probabilities" (12c.), from Latin opinionem (nominative opinio) "opinion, conjecture, fancy, belief, what one thinks; appreciation, esteem," from stem of opinari "think, judge, suppose, opine," from PIE *op- (2) "to choose" (see option).

Where there is much desire to learn, there of necessity will be much arguing, much writing, many opinions; for opinion in good men is but knowledge in the making. [Milton, "Areopagitica"]
