Relating to Azerbaijan or its people, language, or culture; a person from Azerbaijan.
From Azerbaijan (itself from Persian 'Āzarbāijān,' possibly meaning 'land of fire' due to natural gas fires on hillsides) with English adjectival suffix '-ese' commonly used for nationalities.
The suffix '-ese' originally came from Latin and got adopted into English to describe languages and nationalities (Japanese, Chinese, Vietnamese), and it's still our go-to way to name languages even though it's a bit old-fashioned!
