The English language can be so confusing. Past and passed are words that are easily mixed, especially in writing.
However, the quickest way to remember how to use the two words is this: Past is used as a noun, adjective, adverb, or preposition. Passed is used as a verb.
For example: I don’t like to think about my past. (Noun)
For example: Joan read two books this past week. (Adjective)
For example: The editor ran past and almost knocked me over. (Adverb)
For example: We will leave when it is half past the hour. (Preposition)
For example: My son passed the history test. (Verb)
If you are not sure which word to use, simply ask yourself, “is the word passed (past) being used as a verb? If so, you know to use passed. If it isn’t, you know to use past.
