The personal name "Selyk" is derived from the patronymic entry of 1565 - "Selikow" (archive YZR 1/1, 705), which contains an East Slavic diminutive variant of the name Selyk. This variant stems from the root "Sel-," which is also found in full names such as Bulgarian "Selimir" or in models like "Novosel," "Dobrosel."
