“We don't just borrow words; on occasion, English has pursued other languages down alleyways to beat them unconscious and rifle their pockets for new vocabulary.” — James Nicoll

English accepts — even welcomes — many terms from other languages. On occasion, these words or phrases become so thoroughly assimilated into English that they no longer have their foreign flavor. Words like negligee, camaraderie, and entourage are now so commonly used in everyday English that we've forgotten their French etymology. However, due to the historical influence of immigrants and to today's increasing ease of communication, many books, documents, and other material that you may read are infused with foreign words and phrases.
