The spelling of the word "Daviss" can be confusing, as it appears to have an extra "s" at the end compared to the more common spelling of "Davis". However, the extra "s" is actually used to indicate a different pronunciation. In IPA (International Phonetic Alphabet) transcription, "Davis" is pronounced as /deɪvɪs/, while "Daviss" is pronounced as /deɪvɪsəs/. The "əs" sound at the end indicates a slightly longer pronunciation of the final "s" sound.
