The word "curasso" is commonly misspelled as "curacao." However, the correct spelling is "curaçao," with a cedilla under the "c." This special mark signals that the "c" should be pronounced as an "s" sound. The IPA phonetic transcription for "curaçao" is /kjuːrəˈsaʊ/, where the "ç" is represented by the symbol /s/, the "au" is pronounced as in "saw," and the stress falls on the second syllable (/ə/ represents the schwa sound). So next time you order a Blue Curaçao cocktail, make sure to spell it correctly!
