An opinion is a personal view, attitude, or appraisal; a belief or judgment that is not based on what is absolutely certain.
We use them to express ourselves.
- Do we have an opinion about everything? If not, should we? @ TED – ideas worth spreading
Excerpt: An opinion does say everything about our identity, and so it should! An opinion is personal, it’s the way we express our thoughts and feelings towards anyone and anything!
- Opinion @ Wikipedia
Excerpt: In general, an opinion is a belief about matters commonly considered to be subjective, i.e., it is based on that which is less than absolutely certain, and is the result of emotion or interpretation of facts. An opinion may be supported by an argument, although people may draw opposing opinions from the same set of facts. Opinions rarely change without new arguments being presented. It can be reasoned that one opinion is better supported by the facts than another by analyzing the supporting arguments. In casual use, the term opinion may be the result of a person’s perspective, understanding, particular feelings, beliefs, and desires. It may refer to unsubstantiated information, in contrast to knowledge and fact-based beliefs.
