The spelling of the word "supernaw" is unusual, and it can be confusing to know how to pronounce it. The correct phonetic transcription is /suːpərnɔː/. The first syllable is pronounced like "soup," and the second syllable rhymes with "born." The "naw" ending is spelled with an "a" instead of an "o" like in the word "know" which may throw some readers off. However, with the proper IPA transcription, it becomes clear how to spell and pronounce this unique word.
