The influence of Anglo-Norman was very asymmetric: very little influence from English was carried over into the continental possessions of the Anglo-Norman kings. Some administrative terms survived in some parts of mainland Normandy: (from "furrow", compare "furlong") in the Cotentin Peninsula and Bessin, and a 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 with English in later centuries, rather than Anglo-Norman.
