"Wert on top heap" is a phrase with an unusual spelling. The word "wert" is actually an archaic form of the verb "were," meaning "were you." The "w" at the beginning is pronounced as a "v" sound, making the IPA transcription /wɛrt/. The phrase "on top heap" simply means on top of the heap, but with an old-fashioned spelling. While these words may not be commonly spelled this way today, they offer insight into the evolution of the English language over time.
