The correct spelling of the phrase "wert possessed of" is influenced by its archaic origin. "Wert" is an old form of the verb "were," commonly used in Shakespearean English. Meanwhile, "possessed" has a silent "d" at the end, which is a remnant of Middle English. The preposition "of" is pronounced as /ɒv/ in IPA phonetic transcription, with a short "o" sound followed by a "v" sound. Altogether, the phrase is pronounced as /wɜrt pəˈzɛst əv/, with stress on the first and third syllables.
