Faux Pas? [PDF ebook] 
A No-Nonsense Guide to Words and Phrases from Other Languages

If you have ever been bamboozled by the use of a foreign word or phrase, or simply want to spice up your vocabulary with some well-chosen bons mots, then this is the book for you. Thousands of foreign words and phrases have been absorbed into the language and are currently used in English, from the everyday (macho, tete-a-tete, spaghetti) to the relatively obscure (ultra vires, auto-da-fe). Faux Pas focuses on familiar terms and expressions as well as those that are new, curious or amusing. Each expression is  »translated », with an indication of its language of origin and pronunciation, a comment on its usefulness and a Pretentiousness Index.
