The spelling of the phrase "wast possessed of" can be a bit confusing for English learners. In IPA phonetic transcription, it would be written as /wɑst pəˈzɛst əv/. "Wast" is the archaic second person singular of "be," "possessed" means "owned," and "of" is a preposition indicating possession. So, the phrase essentially means "you were in possession of." While this phrase might not be commonly used today, understanding its spelling and meaning can still be helpful in historical or literary contexts.
