opinion

n. attitude; outlook; formal judgement or estimation

An opinion is a person's ideas and thoughts towards something. It is an assessment, judgment or evaluation of something. An opinion is not a fact, because opinions are either not falsifiable, or the opinion has not been proven or verified. If it later becomes proven or verified, it is no longer an opinion, but a fact.
