what is sentence in semantics

In semantics, a sentence is a set of words that is complete in itself, typically containing a subject and predicate, conveying a statement, question, exclamation, or command, and consisting of a main clause and sometimes one or more subordinate clauses. The meaning of the sentence is interpreted based on the meanings of the individual words and the way they are arranged. Semantics is the branch of linguistics that deals with meanings, so in this context, a sentence is a unit of language whose meaning we try to understand.
