The spelling of the word "Kaylley" is unusual and may confuse those who are unfamiliar with it. However, the pronunciation can be explained through the use of IPA phonetic transcription. "Kaylley" is pronounced as "keɪli", with the "k" sound at the beginning, followed by the long "a" sound, then the "l" sound, and finally the "ee" sound. The addition of the "y" serves to make the word visually distinct, although it does not necessarily change the pronunciation.
