Sitnik (surname)

Sitnik is a surname of Slavic origin. It is most commonly found in Poland, Russia, Belarus, and Ukraine.

The etymology of the name is generally believed to be derived from the word "sitnik" (ситник in Russian, сітник in Ukrainian, sitniczek in Polish), which refers to a rush (Juncus) or bulrush (Scirpus) plant. These plants are commonly found in wet or marshy areas. Thus, the surname could have originated as a descriptive name for someone who lived near such an area, worked with rushes (e.g., for weaving), or was associated with a place where rushes grew.

The surname Sitnik may also be derived from a nickname or occupation related to sieves. The Polish word "sitko" means "sieve," so it is possible the surname was used to describe someone who made or used sieves.

Variants and related surnames include: Sitnikov (a common Russian form, typically using the patronymic suffix "-ov"), Sitnikova (the feminine form of Sitnikov), and other localized variations based on regional dialects and transliterations. The surname's frequency and distribution vary across different Slavic countries, reflecting historical migration patterns and demographic changes.
