Central is Latin centrālis, an adjective made from centrum, the centre, which Latin had borrowed from Ancient Greek kentron. Behind both stands the Proto-Indo-European root ḱent-. So a central street and the centre of a circle carry the same Greek word, one of them wearing a Latin adjective ending.
