The correct spelling of the word "wert prodigal with" is actually "wert prodigal wit." The "h" at the end of "with" is not used in this phrase. In IPA phonetic transcription, it would be written as /wɜrt prɑdɪgəl wɪt/. "Wert" is the archaic form of "were" and "prodigal wit" refers to someone who is extremely wasteful with their intelligence or talent. This phrase is often used in Shakespearean literature.
