Answer 2

A sentence that is either true or false is called a Proposition.

• A proposition in logic and linguistics is the definition of a declarative assertion.
• Meaning, according to philosophy, is a non-linguistic entity that all sentences with the same meaning share.
• In other terms, a proposition is a non-linguistic transmitter of truth or falsity that may translate any language into true or false.
• While the term proposition is sometimes used in daily English to refer to a linguistic statement that can be true or untrue, it relates to the statement's non-linguistic meaning rather than its mathematical application.
• In both the history of philosophy and modern analytic philosophy, the phrase is commonly used to refer to a wide range of problems.
