Meaning Is What We Do With It

Ludwig Wittgenstein introduced a different way of thinking about meaning, a common-sense way that identifies meaning with use. The meaning of something is what we do with it. This led to Conceptual/functional/inferential/procedural role semantics.

Similarly, proof-theoretic semantics, spearheaded in the 1940s by the German mathematician Gerhard Gentzen, takes the meaning of a proposition to be defined by the role that the proposition plays within the system of inference.
