Russian patronymic generator
Every Russian has a middle name built from their father's first name: the patronymic, о́тчество (otchestvo). Enter a father's name (Latin letters work) and get the correct form for sons and daughters, stress marked, with the irregular families handled.
How patronymics work
Sons take -ович/-евич (-ovich/-yevich), daughters take -овна/-евна (-ovna/-yevna). A handful of old names ending in -а or -я form them differently: Илья (Ilya) gives Ильич (Ilyich) and Ильинична (Ilyinichna), which is why guessing goes wrong.
For the deeper story (history, etiquette, famous examples), read Russian patronymics explained. For what friends call each other instead, meet the diminutive explorer. Name plus patronymic is the respectful way to address someone: a student calls their teacher Ири́на Петро́вна (Irina Petrovna), never just Ири́на. Women keep their own patronymic for life; it never changes with marriage. And patronymics decline like any Russian noun, so the endings shift with case: see Russian cases explained or look any form up in the declension tool.
Questions
What is a patronymic?
A second name every Russian carries, built from the father's first name: Ivan's son Pyotr is Пётр Ива́нович (Pyotr Ivanovich), his daughter Anna is А́нна Ива́новна (Anna Ivanovna). It sits between the first name and the surname on every official document.
Do Russians have middle names?
The patronymic fills that slot. There is no free-choice middle name; the father's name decides it, with only the son/daughter suffix to pick.
What if the father's name ends in -а or -я?
Those form a small irregular family: Ники́та (Nikita) gives Ники́тич/Ники́тична, Лука (Luka) gives Луки́ч/Луки́нична. The generator knows them; they follow a pattern but not the regular one.
When do Russians actually use it?
Addressing teachers, doctors, officials, older colleagues, in-laws. Among friends it disappears completely. Using name + patronymic with a peer sounds ironic or overly formal, which Russians also use deliberately for humor.
Do women's patronymics change at marriage?
Never. The surname may change; the patronymic is from her father and stays for life.
Names are the doorway
The grammar behind them is the house. Slova trains the vocabulary and case endings that make real Russian sentences work.
