other languages like Spanish—although the usual order of names is "first middle last"—for the purpose of cataloging in libraries and in citing the names of authors in scholarly papers, the order is changed to "last, first middle," with the last and first names separated by a comma, and items are alphabetized by the last name. In France, Italy, Spain, Belgium and Latin America, administrative usage is to put the surname before the first on official documents. Compound surnames While in many countries surnames are usually one word, in others a surname may contain two words or more, as described below. English compound surnames Compound surnames in English and several other European cultures feature two (or occasionally more) words, often joined by a hyphen or hyphens. However, it is not unusual for compound surnames to be composed of separate words not linked by a hyphen, for example Iain Duncan Smith, a former leader of the British Conservative Party, whose surname is "Duncan Smith". Surname affixes Many surnames include prefixes that may or may not be separated by a space or punctuation from the main part of the surname. These are usually not considered true compound names, rather single surnames are made up of more than one word. These prefixes often give hints about the type or origin of the surname (patronymic, toponymic, notable lineage) and include words that mean from [a place or lineage], and son of/daughter of/child of. The common Celtic prefixes "Ó" or "Ua" (descendant of) and "Mac" or "Mag" (son of) can be spelled with the prefix as a separate word, yielding "Ó Briain" or "Mac Millan" as well as the anglicized "O'Brien" and "MacMillan" or "Macmillan". Other Irish prefixes include Ní, Nic (daughter of the son of), Mhic, and Uí (wife of the son of). A surname with the prefix "Fitz" can be spelled with the prefix as a separate word, as in "Fitz William", as well as "FitzWilliam" or "Fitzwilliam" (like, for example, Robert FitzRoy). Note that "Fitz" comes from French (fils) thus making these surnames a form of patronymic. Chinese compound surnames Some Chinese surnames use more than one character. Spanish-speaking world In Spain and in most Spanish-speaking countries, the custom is for people to have two surnames, with the first surname coming from the father and the second from the mother; the opposite order is now legally allowed in Spain but still unusual.
