Lexigraphy refers to the study of words and vocabulary, specifically with regard to their origins, meanings, and usage. Synonyms for this word include lexicology, lexical semantics, and Lexicography. Lexicology is the branch of linguistics that deals with the study of words, their meanings, and their relationships to one another. Unlike lexicography, lexical semantics focuses on the meaning of words as well as their relationships with other words and phrases. In contrast, Lexicography is the art or process of compiling, writing, and editing dictionaries. All of these synonyms refer to the study of words and their usage, but each one has its own unique focus and perspective.
