Than vs. Then: What's the Difference?
Grammar Rule in 30 Seconds
Use 'than' for comparisons and 'then' for time or sequences.
- Use 'than' when comparing two things: 'She is taller than him.'
- Use 'then' for time or order: 'We ate, then we left.'
- Use 'then' for consequences: 'If it rains, then we stay home.'
Overview
At a foundational level, English relies on precise word choices to build meaning, and few pairs illustrate this better than than and then. While separated by only a single vowel, their roles in a sentence are entirely distinct. This distinction is not arbitrary; it stems from their different grammatical functions.
Than is a conjunction, a word whose sole purpose is to connect elements in a comparison. Then is an adverb, a word that modifies verbs and clauses by providing information about time, sequence, or logical result.
Native speakers can distinguish them with ease, but for a learner, their near-identical pronunciation in rapid speech makes them easy to confuse in writing. Mastering the difference is a crucial step for moving beyond basic fluency into a more precise and sophisticated command of English. This guide will provide a systematic breakdown of each word's function, structure, and context, enabling you to use them with confidence.
This is not simply a rule to memorize; it's an insight into how English constructs comparisons and sequences. Understanding their roles as a conjunction and an adverb, respectively, is the key to unlocking their correct usage permanently.
How This Grammar Works
than and then correctly, you must first internalize their core grammatical identities. One compares, the other specifies time or order. Let's analyze each word's specific function and the linguistic job it performs.Than as a ConjunctionThan is a subordinating conjunction used to introduce the second element or clause in a comparison. Its only job is to create a link between two unequal things. Whenever you use a comparative adjective (like taller, faster, more expensive) or a comparative adverb (like more quickly), than is the word that introduces what you are measuring against.Than is the bridge between them.My current project is more complex than the last one.(Comparescurrent projectandthe last one)She speaks English more fluently than I do.(Compares the manner of speaking)
than introduces a subordinate clause (e.g., ...than the last one was, ...than I speak English). In modern English, we often omit the rest of the clause for conciseness, but its grammatical structure as a clause-linker remains.Then as an AdverbThen is an adverb that answers the questions "when?" or "what happens next?". It does not compare things. Instead, it places actions or states in time or a logical sequence. Then has three primary uses, all related to this core function.- 1To Indicate Sequence (Next in order): This is its most frequent use. It shows the progression from one event to another. It signals to the reader or listener that you are moving to the next item on a timeline.
First, you need to complete the online form, then you will receive a confirmation email.
- 1To Refer to a Specific Time (At that time):
Thencan refer to a particular moment in the past or future that has already been established. It acts as a temporal placeholder.
In 2015, the company was much smaller. We had only ten employees then.(Here,then= 'at that time' or 'in 2015')The meeting is at 3 PM. I will be ready to present then.(Here,then= 'at 3 PM')
- 1To Show Logical Consequence (In that case / As a result): This usage connects a condition to a result. It’s often used in
if...thenconstructions, but theifclause can also be implied.
If you have finished your work, then you are free to go home.- (To a friend who says they are hungry)
You're hungry? Then let's get something to eat.(Here,thenmeans 'in that case' or 'as a result of you being hungry')
Formation Pattern
than or then. Understanding these patterns provides a practical framework for building your own correct sentences.
Than
Than almost always follows a comparative form. The basic structure is consistent.
than + Noun 2 | This laptop is faster than my old one. |
more/less + Adjective + than + Noun 2 | The movie was more interesting than the book. |
than + Clause/Noun | He finished the race more quickly than everyone else. |
Rather + Verb + than + Verb | I would rather drive than take the train. |
Other + than | She has no other options than to accept the offer. |
Then
then is more flexible in its placement. Its position depends on its function (sequence, time, or consequence).
then Clause 2. | We reviewed the data, then we made a decision. |
Then, second action. | Log into your account. Then, navigate to the settings page. |
then. | The price of flights was much lower back then. |
then-adjective, noun | The then-CEO of the company made the announcement. (Used as a hyphenated adjective before a noun) |
If...then) | If [Condition], then [Result]. | If the data is correct, then our strategy is working. |
Then, [Result]. | The alarm didn't go off. Then, that's why you're late. |
than is rigid in its role, always tied to a comparison. Then is a versatile adverb that can move around the sentence to modify the timing or logic of the action.
When To Use It
than and then is dictated entirely by the context of your communication. Here is how they appear in various real-world situations.than for Comparisons, Opinions, and Preferences.than is the necessary word. This is common in academic writing, professional analysis, and everyday decision-making.- In a Work Email:
After reviewing both proposals, I believe Option A offers a better long-term value than Option B, despite the higher initial cost. - In University Discussions:
Marx's theory of alienation is arguably more influential in sociology than his economic predictions. - In Casual Texting:
Honestly, I'd rather stay in tonight than go to that party. - Expressing a Preference:
I find that listening to podcasts is more relaxing than watching TV.
then for Sequences, Instructions, and Results.then is the correct choice. It organizes information according to a timeline or cause-and-effect.- In Project Management:
We will gather the user requirements first. Then, we will create the wireframes and mockups for client approval. - Giving Technical Support:
First, clear your browser's cache. Then, restart the application. - Recounting a Story:
I was just about to leave my house, and then I realized I had forgotten my keys. - In Logical Reasoning:
The defendant has no alibi. If that's true, then he must be the primary suspect.
then. If you are using a word like more, less, better, or worse, you almost certainly need than.Common Mistakes
than and then are common even among native speakers in casual writing, but are considered basic errors in formal or professional contexts. Understanding the typical pitfalls is the best way to avoid them.- 1The Standard Mix-up: This is the most frequent error, caused by their similar sounds.
- Incorrect:
My new phone has a better camera then my old one. - Why it's wrong: The sentence is a comparison, triggered by the word
better. It requires the conjunctionthan. - Correct:
My new phone has a better camera than my old one.
- Incorrect:
We went for a long walk, and than we got ice cream. - Why it's wrong: The sentence describes a sequence of events. It requires the adverb
then. - Correct:
We went for a long walk, and then we got ice cream.
- 1The Pronoun Case after
than: This is a more advanced grammatical point. Becausethanis a conjunction that introduces a clause, the pronoun that follows it should technically be in the subject case (I,he,she,we,they).
- Formal/Correct:
You are much taller than I.(The implied full clause is...than I am.) - Informal/Common:
You are much taller than me. - Guideline: In formal writing (academic papers, business reports), using the subject pronoun (
than I) is preferred. In everyday speech and informal writing, the object pronoun (than me) is extremely common and widely accepted. Treatingthanas a preposition that takes an object is now a normal feature of informal English.
- 1Confusion in the phrase
different than: The phrasedifferent fromis traditionally considered the most formal and correct choice in British English. However,different thanis standard in American English, especially when a clause follows.
- Formal (BrE/AmE):
My experience was different from yours. - Standard (AmE):
My experience was different than yours. - Widely Accepted (esp. with a clause):
The city looks very different than I remember.
- 1Redundant
theninif...thenconstructions: In many cases, the wordthenis not strictly necessary after anifclause, especially in speech.
- With
then:If you are late, then you will miss the introduction. - Without
then:If you are late, you will miss the introduction. - Guideline: Both are correct. Using
thenadds emphasis and formality, making the logical connection more explicit. Omitting it can make the sentence flow more naturally in casual conversation.
Real Conversations
Seeing than and then in natural dialogue helps solidify the difference between them. Notice how the context of comparison versus sequence makes the choice clear.

Quick FAQ
then to mean 'in that case'?Yes, this is a very common and correct use of then. It shows a logical consequence. For example: "The roads are closed." "Okay then, we'll have to take the train."
then used as an adjective, like the then-president. Is that correct?Yes, this is a standard and slightly formal use. Then can be used as an adjective before a noun to mean "at that particular time." For example, The report was submitted to the then-director of the department. It signifies that the person held that title at that past time, but may not hold it now.
now and then?This is a fixed idiom. Now and then means "occasionally" or "sometimes." For example, I don't see my university friends often, but we meet for dinner now and then. In this phrase, then retains its meaning of 'at another time.'
Yes, although it can be subtle in fast speech. Than is typically pronounced with a short 'a' sound /ðæn/, as in pan. Then is pronounced with a short 'e' sound /ðɛn/, as in pen. Focusing on this mouth shape (a vs. e) can help you distinguish them, but be aware that in unstressed situations, they can sound very similar.
than to then or vice versa. Why?Autocorrect algorithms are predictive and based on common patterns, but they don't truly understand the grammar of your sentence. If you write a sequence of events, it might incorrectly suggest than, or if you type a comparative word, it might guess then. It's a useful tool, but you must be the final proofreader. Your grammatical knowledge is more reliable than the software's suggestion.
Other than is a common fixed phrase that acts like a preposition meaning "except" or "besides." For example: The office was empty other than the security guard. It introduces an exception to a general statement. Do not confuse it with a direct comparison.

Smart Tips
Check if you can replace the word with 'in comparison to'. If yes, use 'than'.
Check if you can replace the word with 'next'. If yes, use 'then'.
Always pair 'rather' with 'than'. It's a fixed team.
Treat 'more' and 'less' as magnets that pull 'than' toward them.
Pronunciation
The Schwa Reduction
In casual speech, both 'than' and 'then' are reduced to /ðən/. You must rely on context to understand which is being used.
Emphasis
When stressed, 'than' sounds like /ðæn/ (rhymes with 'pan') and 'then' sounds like /ðɛn/ (rhymes with 'pen').
Comparative Stress
It's BETTER than that.
Stress falls on the adjective, making 'than' very short.
Sequential Stress
And THEN what?
Stress on 'then' to show surprise or request more info.

Challenge
Write three sentences about your morning routine using 'then' and two sentences comparing your home to your office using 'than'.
Cultural Notes
Native speakers make this mistake constantly in informal writing (social media). Using it correctly is a sign of high literacy.
In formal logic and mathematics, 'if-then' is the standard. Omitting 'then' is common in casual speech but 'then' is often kept for clarity in complex proofs.
In some dialects, 'than' might be pronounced more like 'then', making the distinction even harder for local learners.
Both words derive from the Old English word 'thanne' or 'thonne'.

FAQ (8)
No. In standard English, 'then' is never used for comparison. This is a very common spelling error, but grammatically, they are distinct.
Both are used. 'Better than me' is common in casual speech. 'Better than I (am)' is more formal. In both cases, you use `than`.
In English, unstressed vowels often turn into a 'schwa' sound /ə/. Since 'than' and 'then' are usually not the most important words in a sentence, they both get shortened to /ðən/.
In this case, 'then' acts as an adjective meaning 'at that time'. It refers to the person who was president at the time being discussed.
Only if 'more' is the end of one thought and 'then' starts a new one: 'I couldn't take any more. Then, I left.' But for comparison, it is always 'more than'.
Think of the letters: Th**a**n = **A** comparison. Th**e**n = Tim**e**.
Yes, they are very similar. 'I'd rather have tea than coffee' means the same as 'I'll have tea instead of coffee'.
Rarely. 'Than' usually follows a comparative word. 'Then' starts sentences all the time (e.g., 'Then, we went home.').
