Confusing “Than vs Then” is one of the most common slip-ups in English. These two words may look and sound similar, but they play very different roles in sentences. Knowing the difference between than and then is essential if you want to improve your writing and avoid embarrassing mistakes. Whether you’re crafting emails, writing essays, or posting online, using the right word matters.
In this quick grammar guide, you’ll learn exactly how to use than and then correctly with real-life examples, easy rules, and smart memory tricks. We’ll also clear up common grammar mistakes and help you master these tricky terms once and for all. Let’s get started!
Why the Confusion Happens
Many stumble over grammar comparison words because then and than look alike and come up in similar contexts. One acts as a comparison conjunction or preposition, while the other works as an adverb of time or sequence and conditional logic. Getting the proper grammar usage clear can save you from common grammar mistakes that pop up in writing, exams, emails, and social media posts.
When to Use “Than”
Here, we explore when to use than and how it functions in comparisons, such as “better than” or “older than.” You’ll find scenario examples, synonyms, and quick tips to solidify your grasp of comparative structures and sentence structure.
Purpose: “Than” lets you compare two things in terms of degree or quantity.
Examples:
- “She’s smarter than I am.”
- “I have more books than you.”
- “He runs faster than anyone else here.”
Synonyms:
- Instead of “more than,” use “exceeding.”
- Replace “rather than” with “instead of” in preference contexts.
Tips:
- Ask yourself, is this making a comparison? If yes, use than.
- Spot words like “more,” “better,” “less,” and “older”—these often signal than.
- Remember the mnemonic: “Than” = comparison (both have n).
When to Use “Then”
Now, understand when to use then, which often deals with time sequencing, cause and effect, and conditions. We’ll look at scenarios, synonyms, and English grammar tips to help you get it right every time.
Purpose:
- Time sequence: indicates order of events.
- Conditional statements: like “If… then…”
- Cause and effect: links actions and results.
Examples:
- “We ate dinner, then we watched Netflix.”
- “If you study, then you’ll pass.”
- “Back then, I didn’t know how to code.”
Synonyms:
- For sequencing: “afterward,” “next.”
- For conditions: “therefore,” “consequently.”
Tips:
- Ask does it involve timing, ordering, or cause? If yes, it’s likely then.
- Spot sequence words like “first,” “next,” or “later.”
- A mnemonic: “Then” = time (both have e).
