The spelling of the word "coulouris" may seem confusing at first, but it is actually quite logical when you break it down phonetically. In IPA transcription, it would be written as /kʌlərɪs/. The "ou" combination represents the sound of a short "uh" vowel, while the "r" and "i" are each pronounced separately as in "color" and "is." So, "coulouris" would be pronounced as "kuh-luh-ris." Remembering the phonetic sounds of each letter can help avoid any spelling confusion.
