Words That Express Time, Sequence, and Comparison
Time-related words in English serve double duty: they express when something happens and how things compare. "Then" marks sequence (first this, then that). "Than" marks comparison (bigger than that). "Passed" is a verb describing movement through time. "Past" is a noun, adjective, or preposition referring to a previous period.
These pairs are among the most frequently confused in English because they sound nearly identical in speech. The difference only becomes visible — and critical — in writing.
Time & Progression Words Compared
| Confused Pair | Word A | Word B | Quick Test |
|---|---|---|---|
| Then vs Than | Then = time/sequence (next, afterward) | Than = comparison (more than, rather than) | Is it about time? → then. Comparing? → than. |
| Passed vs Past | Passed = verb (he passed the test) | Past = noun/adj/prep (in the past, past the house) | Can you replace it with "went by"? → passed (verb) |
Why Time Words Matter in Writing
In academic and professional writing, time-word errors signal carelessness. A research paper that confuses "then" and "than" in its analysis section undermines the author's credibility. An email that says "in the passed" instead of "in the past" looks unprofessional.
The fix is simple: pause for half a second at each usage and apply the quick test. Over time, this check becomes automatic.
A Fast Sequence Check
When editing, ask whether the sentence is about order, comparison, or time period. That one decision usually gives away the right word immediately. It also tells you whether the problem belongs in this hub or in a tense-related lesson.

Deep Dive
This hub is for writers who know something about time or comparison feels off but have not yet isolated the real grammar issue. Sometimes the problem is a single word pair such as then/than. Sometimes the wrong tense elsewhere in the sentence makes the pair harder to diagnose. That is why this hub links word choice with sentence-level time control.
A practical route is to begin with Then vs Than for sequence versus comparison, continue to Passed vs Past for verb-versus-time-reference choices, and finish with Tense Consistency if the paragraph still wanders between time frames.
