The spelling of the word "Jacquena" may sound confusing, but it can be explained with the help of the International Phonetic Alphabet (IPA). The first syllable, "Jac", is pronounced as /dʒæk/, with the 'j' sound represented by the IPA symbol /dʒ/. The second syllable, "quena", is pronounced as /kweɪnə/, with the 'qu' sound represented by the IPA symbol /kw/. Therefore, the correct spelling of the word is "Jacquena", with a 'q' instead of a 'c' in the second syllable.
