“Wherefore” is an old-fashioned word that basically means “why” or “for what reason.”

What Does Wherefore Mean?

Core meaning (short answer)

  • As an adverb, wherefore = “why” or “for what reason.”
  • As a noun, it can mean “the reason” (as in “the whys and wherefores”).
  • It’s considered archaic and is rarely used in modern everyday English.

So, “wherefore did you do that?” = “why did you do that?”

The famous Romeo & Juliet line

People often think “Wherefore art thou Romeo?” means “Where are you, Romeo?” but it actually means “Why are you Romeo?” (i.e., why are you from the rival family, the Montagues?).

In Shakespeare’s English, wherefore literally meant “for what (reason),” so Juliet is asking why fate made him who he is, not looking around for his physical location.
