A proposition is that part of the meaning of a clause or sentence that is constant, despite changes in such things as the voice or illocutionary force of the clause.
A proposition may be related to other units of its kind through interpropositional relations, such as temporal relations and logical relations.
The meaning of the term proposition is extended by some analysts to include the meaning content of units within the clause.
Example: The tall, stately building fell is said to express propositions corresponding to the following:
The common content of each of the the following utterances is a proposition:
All these utterances may be analyzed as consisting of a predicate naming an event or state and one or more arguments naming referents that participate in that event or state.
