The spelling of "Philis" is in fact incorrect. The correct spelling should be "Phyllis" (/ˈfɪl.ɪs/), which is a common English female name derived from the Greek word "phullon" meaning "leaf". The two "l" letters in the name are pronounced as a single "l" sound in IPA phonetic transcription (/l/). A mistake in spelling someone's name can be seen as disrespectful, so taking the time to double check is important in showing attention and respect to others.
