The term "inversed" is sometimes misspelled as "in versed," due to its similar-sounding pronunciation. Inversed (IPA: ɪnˈvɜrsd) is the correct spelling, and refers to something that has been reversed or turned upside down. The incorrect spelling "in versed" can be explained using IPA phonetic transcription as "ɪn ˈvɜrst," which shows that the "ed" ending has been replaced with "t" due to confusion with the similar-sounding word "versed" (IPA: vɜrst), meaning experienced or knowledgeable.
