'Caucasus-associated' originates from the word 'Caucasus,' which refers to a region between the Black Sea and the Caspian Sea, and the suffix '-associated,' which means 'connected with.'

The term 'Caucasus' has been used since ancient times to describe the mountainous region, and 'associated' is derived from Latin 'associatus,' meaning 'joined with.'

Initially, it meant 'connected with the Caucasus region,' and this meaning has remained consistent in modern usage.
