Lexicology may be defined as the study of the stock of words in a given language, i.e. its *vocabulary or lexicon, while lexicography deals with the writing, compilation and editing of both general and specialised *dictionaries. Both are derived from Greek lexis (word), lexicos (of/for words). They contribute knowledge to the teaching and learning of vocabulary and to the production and use of dictionaries.
