past vs paste

Past and paste sound alike but mean different things. Use quick rules and examples below to pick the right word in work, school, and everyday writing.

Quick answer: which to use

past is about time, former states, or position. paste is about sticking or inserting (especially copying and inserting on a computer). passed is the past tense of pass and means moved or completed an action.

past = time or former (e.g., in the past; past mistakes; past the corner).
paste = stick/insert or a sticky substance (e.g., paste the text; wallpaper paste).
passed = past tense of pass (e.g., She passed the exam; He passed the ball).

Core explanation

Past acts as a noun, adjective, or preposition tied to time or position: "in the past," "past mistakes," "past the station." Paste is primarily a verb meaning to insert copied text or an actual adhesive substance: "paste the paragraph," "wallpaper paste."

Use passed when describing an action that was completed or movement through something: "She passed me on the stairs."

Hyphenation

Neither past nor paste is normally hyphenated by itself. Hyphens appear in compounds when clarity requires them (for example, past-focused or paste-like), but those are stylistic choices. Don't hyphenate just because the word sounds like two parts.

Spacing

Spacing errors happen when writers break or join words incorrectly. Past and paste are single words. Watch for other pairs where spacing changes meaning (for example, "every day" vs "everyday"). When unsure, keep the standard single-word form for past or paste.

How it sounds in real writing

Work: We missed the deadline because the report focused on past issues, not current risks.
School: The professor pasted the citation into the syllabus from the website.
Casual: He passed by my house yesterday; we had coffee together.

Wrong (Casual): I pasted you the link earlier. Right: I sent you the link earlier. (Use pasted only if you literally inserted it into the message body.)

How to fix your own sentence

Step 1: Identify whether you mean time/position (past), inserting/sticking (paste), or the action of passing (passed).
Step 2: Replace the word and read the full sentence aloud for sense and tone.
Step 3: If the replacement feels awkward, rewrite the sentence to match natural phrasing.

Rewrite (Work): Original: Please paste the lessons learned into the report by Friday.
Rewrite: Please include the lessons learned in the report by Friday.
Rewrite (School): Original: The chapter seems paste the exam scope.
Rewrite: The chapter seems outside the exam scope.
Rewrite (Casual): Original: Is six past okay for dinner?
Rewrite: Is six past okay for dinner? → Better: Is six okay for dinner?

A simple memory trick

Replace the word with a quick stand-in: if "last" fits, use past. If "attach" fits, use paste. If you mean the action of passing, use passed.

past → last (time/position)
paste → attach/insert (copy & insert, or adhesive)
passed → acted/moved (past tense of pass)

FAQ

Is it 'paste' or 'past' when I mean 'earlier'?

Use past. "In the past" and "past events" are correct for earlier time.

Can I say 'I pasted you the document' in an email?

Only if you literally inserted copied content into the message body. More commonly, say "I sent the document" or "I've attached the document."

How do I remember which is which quickly?

Mnemonic: past = last (time); paste = attach/insert (sticky). Swap in "last" or "attach" to test which fits.

Is 'pasted' the same as 'past'?

No. "Pasted" is the past tense of paste (inserted). "Past" is a noun, adjective, or preposition about time or position.

What about 'passed' - how is that different?

"Passed" is the past tense of pass (e.g., "She passed the test"). Use passed for completed actions or movement; use past for time or position.
