"I still don't know what Episcopalian means"

In this quote, Fiona Apple is expressing her confusion and lack of understanding about the term "Episcopalian." It could be translated as an amusing or lighthearted remark, as if she is satirizing herself for not knowing the meaning of the word. It could likewise suggest that she is not familiar with the Episcopalian religion or denomination, and is admitting her ignorance. This quote could also be viewed as a reflection of the complexity and diversity of faiths and practices, as even somebody as popular and talented as Fiona Apple can still be uncertain about specific terms or concepts.
