Anglo-Norman language general use of the word "acre" for land measurement in Normandy until metrication in the 19th century, but these words are probably linguistic traces of Saxon or Anglo-Scandinavian settlements between the 4th and the 10th centuries in Normandy. Otherwise the direct influence of English in mainland Norman (such as "smogler" - to smuggle) is from direct contact in later centuries with English, rather than Anglo-Norman. When the Normans invaded England, Anglo-Saxon literature had reached a very high level of development. The important Benedictine monasteries both wrote chronicles and guarded other works in Old English. However, with the arrival of the
Anglo-Norman language has been spelled as "s'uvisera" and "s'advisera", and "Reyne" as "Raine". Among important writers of the Anglo-Norman cultural commonwealth is Marie de France. Much of the earliest recorded French is in fact Anglo-Norman French. In Northern France, almost nothing was at that time being recorded in the vernacular because Latin was the language of the Church and consequently of education and historiography, and was thus used for the purpose of records. Latin also remained in use in medieval England by the Church, the royal government and much local administration, as it had been before 1066, in parallel with Middle English.
