Lexicography is a discipline that involves compiling, writing, or editing dictionaries. Lexicography is widely considered an independent scholarly discipline, though it is a subfield within linguistics.

There are two kinds of lexicography - Theoretical Lexicography and Practical Lexicography.

The analysis or description of the vocabulary of a particular language, and the meaning that links certain words to others in a dictionary, is known as Theoretical Lexicography. Theoretical Lexicography is particularly concerned with developing theories regarding the structural and semantic relationships among words in the dictionary. Since it involves theoretical analysis of the lexicon, Theoretical Lexicography is also known as Metalexicography.

The act of writing, or editing dictionaries is known as Practical Lexicography.
