The word "rackauckas" is a tricky one to spell phonetically due to its unfamiliar pronunciation. Its IPA transcription is [rəˈkaʊkəs], which indicates that the 'r' is pronounced as a syllable with a schwa vowel in between 'r' and 'a'. The 'a' sounds like 'ow' in "cow", while the 'ck' and 'k' are pronounced distinctly. The second 'a' has an unstressed schwa vowel sound, and the final syllable is pronounced with a hard 's' sound. Despite its complexity, the spelling of "rackauckas" is consistent with English phonetic rules.
