Where did the word “kukush” come from?

The word "kukush" is believed to have originated from the Romani language, which is spoken by the Romani people, a traditionally nomadic ethnic group of Europe. It is thought to have been derived from the Romani word "kukur", which means "dog". This is likely due to the fact that dogs were often used by the Romani people to guard their campsites and belongings while they traveled. Over time, the word was shortened to "kukush" and adopted into other languages, including English, as a term for "dog".
