In IPA phonetic transcription, "COMMISSION" is spelled as /kəˈmɪʃən/, with the stress on the second syllable. Paying attention to correct spelling is important, as it ensures effective communication and prevents confusion. To avoid misspelling words, it's necessary to take time to double-check spelling and use resources like dictionaries and grammar guides.
