The term lexicography comes from Greek roots, composed of “lexikos” which alludes to the relativity of the word, plus the suffix “ia” which refers to quality; however, other sources state that this word specifically comes from the word lexicográphos, because it was created from the art of a lexicographer, formed by «λεξικόν» or «lexikós» and «gráphos» or «γραφος», which means «to write ». Lexicography is exposed as a reference of a technique or activity that is based on the composition or elaboration of dictionaries or lexicons; that is, this is also described as the discipline of collecting words that must be immersed in a lexicon.

In the linguistic field, lexicography is pointed out as a science that deals with the study and investigation of signs and how they can form possible words; This branch of linguistics proposes to implement the applicable methods for the writing and creation of dictionaries of any kind.

This ancient discipline intends to investigate a systematic collection and explanation of each of the words, also exposed as lexical units, of a certain language, but almost always in breadth rather than in depth, a fact that allows its discipline to be a brother of the lexicology. what these so-called lexical units comprise are not only individual words but also those compound words, idioms to dependent morphemes, which are those that adhere to another morpheme in order to give meaning to the word.

Lexicography as a discipline is not only limited to gathering words for the creation of dictionaries; that is, it also includes a series of theoretical analysis, this is what is known as metalexicography or theoretical lexicography, this goes beyond the origins of dictionary production, typology, aspects related to its formal structure, compilation methods, among others. others.
