IN PRP then (than) IN PRP

Writers often swap then and than because they sound alike. The swap changes meaning: then marks time, sequence, or result; than marks comparison.

Quick answer: When to use then vs. than

Use than for comparisons. Use then for time, order, or consequence.

Comparison? Use than (taller than, more than, rather than).
Sequence/time or result? Use then (first X, then Y; if X, then Y).
Quick tests: substitute "compared to" - if it fits, use than. Substitute "after that" - if it fits, use then.

Core explanation: the grammatical difference

Than introduces comparisons or marks the second item in a comparison. Then indicates time, sequence, or consequence.

If the sentence answers "compared to what?" it's probably than. If it answers "what happened next?" or "when?" it's then.

than = comparison (degree, amount, preference).
then = time, sequence, or consequence.

Comparison: She earns more than I do.
Sequence: Finish the build, then run the tests.
Consequence: If it rains, then we'll move the meeting inside.

Memory tricks and quick checks

Fast checks you can run while skimming or speaking aloud.

Substitute "after that" - if it fits naturally, choose then.
Substitute "compared to" - if it fits, choose than.
Mnemonic: than = comparison (think "a" for amount/advantage), then = time (think "t" for time).

Test: "I'd rather go X then Y." Try "I'd rather go X compared to Y" → doesn't fit, so use than.
Test: "We finish the call then send the report." Try "We finish the call after that, send the report" → fits, so use then.

Fix your sentence: rewrites you can copy

When swapping words makes a sentence awkward, use one of these rewrites to preserve meaning and improve clarity.

She's funnier then me. → Formal: She's funnier than I am. →
Casual: She's funnier than me.
Finish the report no later then Monday. → Please finish the report no later than Monday.
I'd choose pizza then burgers. → Better: I'd choose pizza rather than burgers. → Short: I prefer pizza to burgers.
More people prefer coffee then tea. → More people prefer coffee than tea.
If you sign, then we'll begin. → If you sign, we'll begin. (Comma optional; "then" adds emphasis.)

Try your own sentence

Test the whole sentence rather than the phrase alone - context usually makes the right choice clear.

Spacing, typography, and keyboard slips

Even a correct word can be missed if spacing or autocorrect interferes. Catch these predictable problems.

Search for " then " and " than " (with spaces) to find mistaken uses inside sentences.
Add a comma before then when it begins an independent clause: We finished, then we left.
Add than to your dictionary if autocorrect repeatedly changes it.

Typography: No later then two days after receipt. → No later than two days after receipt.
Autocorrect fix: Add "than" to your personal dictionary or disable aggressive replacements.

Hyphenation, punctuation, and grammar pitfalls to watch

Small punctuation or parallelism errors often accompany then/than slips.

Keep comparisons parallel: "She is smarter than he is" or "smarter than him" (informal).
Use commas with then when linking two independent clauses: "The test ended, then students left the room."
Watch elision: "She is taller than I (am)." The verb can be implied, but the comparison remains.

Parallel: Wrong: He likes running more then to swim. →
Right: He likes running more than swimming. (Or: He likes running more than he likes swimming.)
Comma_then: Right: The test ended, then students left the room.

Similar mistakes and quick corrections

When you see one small-word error, scan for others that commonly appear in the same drafts.

their / there / they're - check possession vs. location vs. contraction.
its / it's - replace with "it is" to test for it's.
to / too / two - confirm direction, addition, or number.

Confusable: Its time to decide rather then hesitate. → It's time to decide rather than hesitate.
Confusable2: Accept all than reject none. → Accept all; reject none. (Or rewrite for clarity.)

FAQ

Can I ever use then in a comparison?

No. If the sentence compares two things or degrees, use than.

Is "rather then" correct?

No. Use "rather than." If it still sounds awkward, try "I prefer X to Y" or another rewrite.

How can I proofread faster for then/than mistakes?

Scan for short modifier + then patterns ("more then", "rather then", "less then"). Use the "after that" / "compared to" tests and search for " then " and " than " physically.

Why does autocorrect change than to then?

Autocorrect favors frequent patterns. Add "than" to your dictionary or adjust substitution settings.

Will switching to than always fix my sentence?

Not always. If the sentence still sounds wrong after the swap, rewrite for parallel structure or use a clearer phrasing (e.g., "prefer X to Y").

Need a quick double-check?

When in doubt, run the two substitution tests ("after that" vs. "compared to") or paste the sentence into a context-aware checker. Use corrections as mini-lessons until the right choice feels automatic.
