The spelling of the word "xxx" can be a bit confusing due to its phonetic complexity. Its pronunciation is represented as /ɛksɛksɛks/ in IPA phonetic transcription, with each "x" representing the sound /ks/. One way to remember the spelling is to break it down syllabically: ex-ex-ex. Another tip is to think of it as a triple repetition of the letter "X" rather than three separate letters. Regardless, mastering the spelling of "xxx" is useful in contexts such as online messaging and adult content warnings.
