Neologisms are words and terms that have recently been "coined" and generally do not appear in any dictionary. Avoid using neologisms when creating articles on Wikipedia unless they are part of the subject being covered and need to be explained; in such a case, be sure to define the new words! Neologisms include words made up on the spot and these should never be used in a Wikipedia article. Wikipedia relies on established English to explain its subjects. It is important that every word in Wikipedia can be understood by those who read it. This ensures that Wikipedia always conveys accessible and meaningful knowledge.
This page is written in British English, which has its own spelling conventions (colour, travelled, centre, defence, artefact, analyse) and some terms that are used in it may be different or absent from other varieties of English. According to the relevant style guide, this should not be changed without broad consensus.
