Why

Oxford: passed is only ever the past tense of the verb pass; past is never a verb. If the sentence needs a verb ("she ___ the exam"), the word is passed; after a verb of motion ("walked ___ the shop"), the word is past.

Examples

  • She passed the exam on her first attempt.
  • We walked past the old station.
