Norman or Norman French is, depending on classification, either a French dialect or a Romance language which can be classified as one of the Oïl languages along with French, Picard and Walloon. The name "Norman French" is sometimes used to describe not only the Norman language, but also the administrative languages of Anglo-Norman and Law French used in England. For the most part, the written forms of Norman and modern French are mutually intelligible. This intelligibility was largely caused by the Norman language's planned adaptation to French orthography (writing).
