delaration

Declaration is a broad term with multiple meanings depending on the context. In law, a declaration is a formal statement or announcement of a fact or intention. This can include a declaration of independence, a declaration of war, or a sworn declaration made under penalty of perjury. In programming, a declaration is a statement that introduces a name and associates it with an entity such as a variable, type, or function. This tells the compiler or interpreter about the existence and nature of the named entity.

The concept of declaration also appears in philosophy and linguistics. In philosophy, a declaration can refer to an assertion or a speech act that makes something true by virtue of its utterance, such as a marriage vow or a royal decree. In linguistics, a declarative sentence is a sentence that makes a statement or declaration, as opposed to an interrogative (question) or imperative (command) sentence. The common thread across these various uses is the act of formally stating or making something known. The specific implications and requirements of a declaration are determined by the domain in which it is used.
