The spelling of the word "de spoiler" may seem confusing to some, but can be easily explained using IPA phonetic transcription. The word is derived from the term "spoiler," which refers to something that ruins the surprise or ending of a book, movie, or TV show. "De spoiler," on the other hand, means to undo or reverse the spoiler. Its pronunciation is /diː ˈspɔɪ.lər/, where the "de" is pronounced as "dee" and the stress is on the second syllable, as in "spoiler."
