The word “opinion” traces its origins back to Latin and has evolved through several languages before entering English.

1. Latin Origin: The term originates from the Latin word opinio, which means “opinion, conjecture, supposition, belief.” This noun is derived from the Latin verb opinari, meaning “to think, judge, suppose.”

2. Proto-Indo-European Root: The Latin opinari is believed to come from the Proto-Indo-European root *op-, which means “to choose” or “to believe.” This root emphasizes the act of choosing or selecting a belief among various possibilities.

3. Old French Influence: The Latin opinio evolved into the Old French word opinion during the Middle Ages. Old French was a significant conduit for Latin words entering the English language after the Norman Conquest of England in 1066.

4. Middle English Adoption: The Old French opinion was adopted into Middle English as opinion around the 14th century. It retained its meaning related to personal beliefs or judgments not necessarily based on fact or knowledge.

Summary:

• Latin: opinio (opinion, belief) ← opinari (to think, suppose)

• Proto-Indo-European: *op- (to choose, believe)

• Old French: opinion (opinion)

• Middle English: opinion (belief, judgment)

The evolution of “opinion” reflects the human practice of forming beliefs and judgments by choosing among different ideas or interpretations.
