What does ''Chernyavsky'' mean in English?

Answer 1

Nothing, it's a last name. It has the Russian word for "black" or "dark" in its root.

Russian names generally don't "mean" anything. The origin of the name is given as either

- someone who came from a town or lived near a river of Chernyava

- a descendant of a dark-skinned, dark-haired person

- a descendant of a female house servant used for dirty ("black") work
