Bilbao is a proper noun for a major Basque city in northern Spain. In English, it’s typically pronounced with two syllables, stress on the second syllable, and the initial “Bil-” sounding like bill; the final “-bao” approximates the Basque pronunciation, ending with a rounded, open vowel. The name is widely used in travel, business, and cultural contexts. It’s not an English loanword with a single fixed pronunciation, so slight regional variation exists.
