Use passed only as the past tense or past participle of the verb “to pass” (she passed the exam). Use past as a noun, adjective, or preposition referring to time before now (in the past; the past decade; walk past the shop).
The Core Difference
“Passed” is always a verb form — if you can rephrase the sentence using another tense of “to pass” (pass, passing), then “passed” is correct: he passed the ball, she passed away peacefully.
“Past” is never a verb. It functions as a noun (learn from the past), an adjective (the past week), or a preposition/adverb of movement (walk past the station, it's half past three).
- verb form (past tense of pass) → passed: passed the test, time passed quickly
- noun/adjective/preposition (time or movement) → past: in the past, walk past the shop

Common Mistakes
| Incorrect | Correct | Why |
|---|---|---|
| ✗ time past quickly this afternoon | ✓ time passed quickly this afternoon | verb, past tense of pass |
| ✗ she past her exam | ✓ she passed her exam | verb form |
| ✗ we drove passed the school | ✓ we drove past the school | preposition of movement |
| ✗ in the passed, people wrote letters | ✓ in the past, people wrote letters | noun, time before now |
| ✗ the passed few weeks were busy | ✓ the past few weeks were busy | adjective, time period |
PASSED has -ED, like every regular past-tense verb (walked, talked, passED). PAST has no -ED because it is never a verb — it's only a noun, adjective, or preposition.

Frequently Asked Questions
What is the one-question test for passed vs past?
Ask: is this word acting as a verb (describing an action that happened)? If yes, use “passed”. If the word describes a time period, a location relationship, or functions as a noun, use “past”.
Can past ever be a verb?
No — “past” is never used as a verb in standard English. Any verb use referring to the action of passing always takes the form “passed”.
What does half past three mean?
“Half past three” means thirty minutes after three o'clock, using “past” as a preposition of time.
Is drove past the house correct?
Yes — “past” functions here as a preposition describing movement alongside or beyond something, not as a verb.
Why do people confuse passed and past so often?
Because they are pronounced identically and “past” looks like it could be a shortened past-tense form, even though it never functions as a verb.
Is passed away a polite way to say died?
Yes, “passed away” is a common, gentler way of saying someone died, using “passed” as the past tense of “to pass (away)”.
Can past describe a noun directly, like an adjective?
Yes — “past” can directly modify a noun as an adjective: “past experience”, “past performance”, “the past week”.
Is this pair commonly tested in writing exams?
Yes, because the words are true homophones with entirely different grammatical roles, exams like IELTS and Cambridge English frequently test whether writers can correctly distinguish verb forms from prepositions/nouns like this pair.
Is passed out correct when someone faints?
Yes — “passed out” uses “passed” as the past tense of the phrasal verb “to pass out”, meaning to lose consciousness or briefly faint.
Does past ever take an -ed ending?
No — “past” never adds “-ed” because it is not a verb; only “passed” carries the regular past-tense ending, which is a quick way to check which spelling you need.
