In [[logic]], the '''logical form''' of a [[Statement (logic)|statement]] is a precisely-specified [[Semantics|semantic]] version of that statement in a [[formal system]]. Informally, the logical form attempts to [[Logic translation#Natural language formalization|formalize]] a possibly [[Syntactic ambiguity|ambiguous]] statement into a statement with a precise, unambiguous logical interpretation with respect to a formal system. In an ideal [[formal language]], the meaning of a logical form can be determined unambiguously from [[syntax]] alone. Logical forms are semantic, not syntactic constructs; therefore, there may be more than one [[string (computer science)|string]] that represents the same logical form in a given language.<ref>The Cambridge Dictionary of Philosophy, CUP 1999, pp. 511–512</ref>
