A dialect is a variety of language spoken by a particular group of people. This may include dominant and standardized varieties as well as vernacular, unwritten, or non-standardized varieties, such as those used in developing countries or isolated areas.
The non-standard dialects of a language with a writing system will operate at different degrees of distance from the standardized written form.
According to one theory of the development of French, Francien was chosen out of all the competing oïl languages as an official language (Norman and Picard being the main competitors in the medieval period).

The term Walser refers to those speakers whose ancestors migrated into other Alpine valleys in medieval times, whereas Walliser refers only to a speaker from Upper Valais – that is, the upper Rhone valley. In a series of migrations during the Late Middle Ages, people migrated out of the Upper Valais, across the higher valleys of the Alps.

Dialects in the context of Regional accents of English
Spoken English shows great variation across regions where it is the predominant language. The United Kingdom has a wide variety of accents, and no single "British accent" exists. This article provides an overview of the numerous identifiable variations in pronunciation of English, which shows various regional accents and the UK and Ireland. Such distinctions usually derive from the phonetic inventory of local dialects, as well as from broader differences in the Standard English of different primary-speaking populations.
