English was heavily influenced by the form of Old French spoken by the new Norman ruling class that had migrated to England (known as Old Norman). Over the following decades of contact, members of the middle and upper classes, whether native English or Norman, became increasingly bilingual. By 1150 at the latest, bilingual speakers represented a majority of the English aristocracy, and monolingual French speakers were nearly non-existent.[41] The French spoken by the Norman elite in England eventually developed into the Anglo-Norman language.[42] The division between Old to Middle English can also be placed during the composition of the Ormulum (c. late 12th century), a work by the Augustinian canon Orrm which highlights blending of Old English and Anglo-Norman elements in the language for the first time.[43][44]
