What makes a pan a pain?

AN I

Not available

This clue plays on the phrase "a pain in the pan," which sounds like "a pain in the an I" when spoken aloud. The word "pan" is split into "pan a" (which hints at the word "pan") and "pain," leading to the answer "AN I" as a punny twist. It’s a classic example of how crossword clues use homophones and misdirection to trick the solver.
