Other forms: opinions
An opinion is what one person thinks about something, which others may reasonably disagree with. In my opinion, a strong opinion, public opinion.
The distinction from a fact is the whole point of the word, and it is worth being clear about: opinions can be argued with and facts can only be checked. The prepositions are fixed — an opinion on or about a subject, and an opinion of a person or thing, which is a judgement of its quality. A second opinion is another expert's view, especially a doctor's. And public opinion is what the population as a whole thinks, measured by polling and argued about endlessly.

Latin opinio comes from opinari, to think or suppose. The word has never claimed more than that — an opinion is a supposing — which is why in my opinion is a hedge rather than a claim.
