The Moon Is a Harsh Mistress is a Hugo Award-winning 1966 science fiction novel by Robert A. Heinlein. Narrated by the protagonist, Manuel ("Mannie") Garcia O'Kelly-Davis, a fairly typical "Loonie," primarily interested in "beer, betting, women, and work," the book throughout has a choppy, staccato style, omitting pronoun subjects of sentences and most indefinite articles. He speaks Australian slang ("dinkum" means "true") and uses Russian words and phrases, peculiarly transliterated with Australia's broad vowels in mind. Only some are explained in context. Dialog is used heavily, and Professor Bernardo de la Paz, though a native of Peru, speaks refined, formal English, and at one point warns Davis against using Lunar slang when talking to Terran officials. Stuart Rene ("Stu") LaJoie, a noble Frenchman, also speaks formal English, proving the narrator is capable of reproducing it, but chooses to write as he and fellow Loonies normally speak. Only once does he imitate a Terran dialect of English.
