Semantics is the branch of linguistics and philosophy concerned with meaning, understanding how language represents and conveys meaning to its users. It involves the study of how words, phrases, and sentences are used to convey meaning in context and how listeners interpret these meanings.
Morphology is the branch of linguistics concerned with the structure and form of words in a language, including the study of morphemes, which are the smallest units of meaning. It explores how words are formed, how they relate to other words in the same language, and how they convey meaning.
