Qetesh was a goddess who was incorporated into the ancient Egyptian religion in the late Bronze Age. Her name was likely developed by the Egyptians based on the Semitic root Q-D-Š meaning 'holy' or 'blessed,' attested as a title of El and possibly Athirat and a further independent deity in texts from Ugarit.

Q-D-Š is a triconsonantal Semitic root meaning "sacred, holy", derived from a concept central to ancient Semitic religion. From a basic verbal meaning "to consecrate, to purify", it could be used as an adjective meaning "holy", or as a substantive referring to a "sanctuary, sacred object, sacred personnel."
