Demchuk

Demchuk is a Ukrainian surname. It is a patronymic surname, derived from a shortened or diminutive form of the given name Demyan (Damian). The suffix "-chuk" is a common Ukrainian suffix indicating "son of" or "descendant of." Therefore, Demchuk essentially means "son of Demyan" or "descendant of Demyan."

The surname is relatively common in Ukraine and among Ukrainian diaspora communities. The spelling may vary slightly depending on transliteration conventions, such as Demczuk or Demchuk.

The name Demyan itself has Greek origins (Damianos) and means "to tame" or "to subdue." It was the name of several early Christian saints.
