Ukrainian surname

Ukrainian surnames can be easily recognized by the most common suffix -enko (Shevchenko, Hordiyenko, Tereshchenko) or less common -ko (Sirko, Pavlychko, Boiko). Another common suffix in surnames that reflects the Ukrainian origin is -chuk (Polishchuk, Palamarchuk, Balanchuk) or its simplified versions -yuk or -yak and -ak (Palahnyuk, Mochulyak, Romanyuk). Suffixes -ko and -uk/yuk are considered to be patronymic.
