The word "CASUPROVISO" may seem confusing at first, but its spelling follows standard English phonetic rules. Pronounced as /kəsuːprəvaɪzoʊ/, this word features a unique combination of sounds not typically found in English language. The "ca" sound is followed by a "su" sound, which blends into "proviso." The emphasis falls on "vi" before "so," with the final "o" being pronounced as "oh." Despite its complex spelling, "CASUPROVISO" is a valid English word meaning "with provision."
