opinion

A subjective perspective that contrasts with objective fact. It carries a sense of personal preference or interpretation, often implying that the statement is open to debate rather than being an absolute truth. In casual contexts, it suggests a whim or a bias. In professional settings—such as law or medicine—it shifts toward 'expert opinion,' where the word denotes a high-level synthesis of experience and evidence, though it remains a judgment rather than a mathematical certainty. Compared to 'belief,' an opinion is often more flexible and less tied to identity or faith; it is something one can change after hearing a new argument.
