How Do You Spell CAESI?
Pronunciation: [sˈiːsi] (IPA) 
The spelling of the word "CAESI" might seem strange if you're not familiar with its pronunciation. The IPA phonetic transcription reveals that it is pronounced /ˈsiːzi/, which explains why it's spelled with an "s" instead of a "c". The vowel sound is an "ee" sound, represented by the letter "i". The final "i" is there simply because English words often end in "i". So, while the spelling may seem unusual at first glance, it actually follows common English spelling patterns once you know the pronunciation.
