A lexicon is the vocabulary of a person, language, or branch of knowledge (such as nautical or medical). In linguistics, a lexicon is a language's inventory of lexemes. The word "lexicon" derives from the Greek λεξικόν{{#invoke:Category handler|main}} (lexicon), neuter of λεξικός{{#invoke:Category handler|main}} (lexikos) meaning "of or for words".<ref>λεξικός in Henry George Liddell, Robert Scott, A Greek-English Lexicon (Perseus Digital Library). Sc. βιβλίον "book").</ref>

Linguistic theories generally regard human languages as consisting of two parts: a lexicon, essentially a catalogue of a language's words (its wordstock); and a grammar, a system of rules which allow for the combination of those words into meaningful sentences. The lexicon is also thought to include bound morphemes, which cannot stand alone as words (such as most affixes). In some analyses, compound words and certain classes of idiomatic expressions and other collocations are also considered to be part of the lexicon. Dictionaries represent attempts at listing, in alphabetical order, the lexicon of a given language; usually, however, bound morphemes are not included.
