Azerbaijani name  An Azerbaijani name consists of an "ad" (name), "ata adı" (patronymic), and "soyad" (surname). Names are regulated by the Civil Code of Azerbaijan. Besides name and surname, patronymics are also in use, however mostly in legal documents, not in daily use. For example, while Ilham Aliyev is known by his name and surname, his full name is "Ilham Haydar oghlu Aliyev" ("oghlu" means son). Likewise, for women the patronymic form "qızı" (meaning daughter) is used, as in Sakina Abbas qızı Aliyeva. It's prohibited to give insulting, sarcastic or non-gender names to children by law. Children automatically inherit their parents' surname upon registration. However, children may change their surname suffixes by age of 10 by their own will. Full name change is only accepted after turning 18, when citizens can change their name, surname and even patronymic name as Family Code allows. Same law also allows complete removal of surnames leaving only first name and patronymic names, however their legal surname would change to XXX as a standard, to avoid problems with surname-less passports. Azerbaijani names include names with Turkic (e.g. Turkish name), Germanic, Slavic, Persian, Arabic and Caucasian origin. There are several published onomastic dictionaries in Azerbaijani including more than 15.000 names. However, there are officially recorded 180.000 different names in registrar of Ministry of Justice. Names are mostly gender specific, however new females names could be invented by adding "-ə" to a male name (for example, male name Ilham could easily be converted into a female name "Ilhama"). Unlike Turkish names, Azeri name are limited by law to one name per child. However, there are compound names like "Mammadhasan" (made of Mammad and Hasan) or "Aliakber" (made of Ali and Akber). Highly influenced by Russian naming customs, as use of surnames in Azerbaijan started in the 1900s with the Russian Empire; most surnames end with suffixes "-ов" (-ov), "-ев" (-yev) meaning "belonging to". Before Russian rule, Azerbaijanis were known usually by their respective clan or tribal names, but Stalinist rule speeded up arbitrary Russification of these surnames.
