The spelling of the word "more shoo in" can be a bit confusing due to its pronunciation. The correct pronunciation is /ˌmɔːr ˈʃuː ɪn/ with the emphasis on the second syllable of "shoo" and a long "oo" sound in the third syllable. This phrase is commonly used to describe a candidate or team that is almost certain to win. The origins of the expression are debated, but it likely comes from horse racing, where a horse that is a shoo-in is a guaranteed winner.
