The aim of this presentation is to present the immediate results of the imposition of the Norman spelling system upon Late Old English / Early Middle English, as visible in Layamon's Brut. This text, dated to the second half of the thirteenth century, is a curious mixture of contemporary and archaised linguistic material. In particular, the spelling system of the text displays a progressive replacement of Anglo-Saxon patters by those introduced by scribes from the continent. In particular,  the questions of recessive, Anglo-Saxon spellings as well as of paths of preservation and replacement will be addressed.
