If the woman takes her husband's full name, the couple can easily be referred to in writing as "Petőfi Sándor és neje" (Sándor Petőfi and wife), equivalent to the English form "Mr. and Mrs. John Smith". This can be seen on older tombstones in Hungarian cemeteries. By law, children born as Hungarian citizens may bear no more than two surnames (most people have only one; those who have two may hyphenate them). They can also have only one or two given names (religious names not included since they are not official, see above). Given names can be chosen by the parents from an official list of several thousand names (technically, one list for each gender). If the intended name is not on the list, the parents need to apply for approval. Applications are considered by the Research Institute for Linguistics of the Hungarian Academy of Sciences following a set of principles. Thus, names are approved if they are not derogatory or overly diminutive, can be written and pronounced easily, can be recognised as either male or female, etc. Approved names expand the official list, the newest edition of which is regularly published. A lot of recent additions are foreign names, which, however, must be spelled following Hungarian phonetics, e.g. "Jennifer" becomes "Dzsenifer" or "Joe" becomes "Dzsó". Those who belong to an officially recognized minority in Hungary can also choose names from their own culture, whereby a register of given names maintained by the respective minority governance must be observed. If one or both parents of a child to be named are foreign citizens, the given name(s) may be chosen in accordance with the respective foreign law. Outside Hungary, Hungarian names are usually rendered by the Western convention of other European languages. In English language academic publishing, archiving and cataloguing, different manuals of style treat Hungarian names in different ways. The "Chicago Manual of Style" 16th Edition (2010) reverses the Hungarian order to put given name first, but allows all diacritics on the name: When indexing names, Hungarian names are re-inverted so the surname comes first in English indexes, the same as English names. This way of writing names is not used for people who are not Hungarian (or not from another country where Eastern name order is used). For example, "Tony Blair" will stay as "Tony Blair" in Hungarian texts. However, names of historical importance are generally translated and written in the Hungarian way, e.g. "Kálvin János" for John Calvin.
