The spelling of the word "Jenneffer" may be confusing to some due to the presence of double letters. However, with the use of IPA phonetic transcription, the spelling becomes clearer. The word is pronounced /dʒɛnɛfɛr/, with stress on the second syllable. This can be broken down into "jen-e-fər". The double "n" and "f" in the spelling correspond to the double consonant sounds in the pronunciation. So, while the spelling may look tricky, a closer look using phonetic transcription can make the pronunciation and spelling much easier to understand.
