The spelling of the word "semisopor" seems straightforward, but it can be confusing to pronounce for some people. The correct pronunciation is /ˌsɛmiˈsɒpər/. The word is a combination of two Latin roots: "semi-" meaning half and "sopor" meaning sleep. Together, they create a term describing a state between being awake and asleep. The spelling of the word may seem simple, but the combination of sounds can make it tricky to pronounce correctly.
