 Philosophical semantics tends to focus on the principle of compositionality to explain the relationship between meaningful parts and whole sentences.The principle of compositionality asserts that a sentence can be understood on the basis of the meaning of the "parts" of the sentence (i.e., words, morphemes) along with an understanding of its "structure" (i.e., syntax, logic).Further, syntactic propositions are arranged into 'discourse' or 'narrative' structures, which also encode meanings through pragmatics like temporal relations and pronominals.
