The word "CCOSCO" is a combination of four consonants and no vowels. The correct spelling of this word is in fact "KSKS-KOH" or /kɛskskoʊ/. The letter "C" in this case is pronounced as "K" while the letter "O" sounds like "OH". The repetition of the letter combination "CS" and "KS" may seem unusual, but it is not uncommon in some languages to have words with consecutive consonants. It is important to remember that proper phonetic transcription helps in accurately representing the pronunciation of words.
