How did Norman French and Central French contribute different words to English?
The influence of French on the English language following the Norman Conquest of 1066 was primarily driven by Anglo-Norman, a dialect of Old French spoken by the ruling elite in England.123
Because the Normans occupied positions of power in administration, law, and literature, Anglo-Norman became the dominant language of prestige. This led to a linguistic stratification where English often adopted "fancy" or formal French terms for concepts already described by simpler, native English words, creating pairs of synonyms.14
In contrast, Francien—the north-central dialect centered around Paris—gained cultural and political prestige later, particularly after 1300. While Anglo-Norman was the primary vehicle for the initial influx of French vocabulary into English during the medieval period, Francien eventually became the basis for Modern French and exerted its influence as the standard language of France. Consequently, while Anglo-Norman provided the foundational layer of administrative and legal loanwords, later French borrowings often reflected the evolving prestige of the Parisian dialect.231
