Benelux is a name for three small countries in western Europe taken together: Belgium, the Netherlands, and Luxembourg. People use it when they want one word for the group — trade, travel, history, or maps. It is not a country itself, and nobody is “from Benelux” in the way they are from Belgium. Though actually, these three have worked closely for decades, so you will see Benelux on forms, in the news, and in company names. Say it BEE-nuh-lux. In English it is a proper name, so it takes a capital B. The name is a blend of the three country names, not the Latin bene- (“good”) that you see in benefit and benefactor.
