The correct spelling of the word "hibbert" is not clearly defined, as it is not a commonly used word. However, based on its pronunciation in English, it could be spelled as /ˈhɪbərt/ with the stress on the first syllable and the use of the letter 'b' instead of 'bb' to indicate a singular pronunciation of the consonant sound. The IPA phonetic transcription shows that the pronunciation of the word starts with the sound of the letter 'h', followed by the short 'i' sound, and ends with the sound of the letter 't'.
