The spelling of the word "trosper" may seem peculiar to some, but it follows the rules of English phonetics. The IPA transcription of the word is /ˈtrɒspə/, where the "o" sound is pronounced like the "o" in "got" and the "a" sound is pronounced like the "a" in "father." The letter "s" represents the /s/ sound, followed by the schwa sound represented by the letter "e." Finally, the letter "r" is pronounced as a tap or a flap sound, as in "butter" or "ladder."
