The spelling of the word "Keylley" can be confusing, as it does not follow typical English phonetic rules. The correct pronunciation is /ki:li/ with a long "e" sound in the middle. The "ey" combination often results in confusion, as it can represent different sounds in different words. However, in this case, it simply serves to elongate the "e" sound. It is important to pay attention to the specific spelling and pronunciation of words to ensure clear communication.
