The IPA phonetic transcription indicates that the first syllable is pronounced with a long "i" sound (represented by the symbol /aɪ/), followed by the consonant cluster "d" and "ər" sound. Despite its obscurity, it's important to use proper spelling of all words, including those that are lesser-known, to avoid confusion and miscommunication.
