Here are some examples of French words and phrases used by English speakers.
English contains many words of French origin, such as art, competition, force, machine, police, publicity, role, routine, table, and many other Anglicized French words. These are pronounced according to English rules of phonology, rather than French. Around 28% of English vocabulary is of French or Oïl language origin, most derived from, or transmitted by, the Anglo-Norman spoken by the upper classes in England for several hundred years after the Norman Conquest, before the language settled into what became Modern English.
This article, however, covers words and phrases that generally entered the lexicon later, as through literature, the arts, diplomacy, and other cultural exchanges not involving conquests. As such, they have not lost their character as Gallicisms, or words that seem unmistakably foreign and "French" to an English speaker.
The phrases are given as used in English, and may seem correct modern French to English speakers, but may not be recognized as such by French speakers as many of them are now defunct or have a different meaning due to semantic evolution. A general rule is that if the word or phrase retains French diacritics or is usually printed in italics, it has retained its French identity.
