The correct word depends on what you want to say. Than is used when comparing two people, things, or ideas, while then is used to talk about time, order, or what happens next. A simple way to remember this is: if your sentence compares something, use than. If it describes the next step or a point in time, use then.

Pronunciation of Then or Than

Although then and than are spelled differently, their pronunciation is similar in everyday English. This is one reason people confuse them.

Word	IPA (US)	IPA (UK)	Sounds Like
Then	/ðɛn/	/ðen/	“then” (rhymes with when)
Than	/ðæn/ or /ðən/	/ðæn/	Often sounds like “than” or “thun” in fast speech

Spoken English Confusion

In casual conversation, many native speakers pronounce than with a reduced vowel (/ðən/). As a result, then and than can sound almost identical.

For example:

• She’s taller than me.
• We finished lunch, then we left.

The pronunciation may sound similar, but the meaning depends entirely on the sentence.

Pronunciation Tip

When speaking:

• Stress the comparison in than.
• Pause slightly before then when showing the next step or event.

This small habit makes your speech clearer.

Why People Confuse Then or Than

Many writers accidentally replace then with than or vice versa. The mistake is common because of several reasons.

1. Similar Spelling

The words differ by only one letter.

• then
• than

A quick glance can easily miss the difference.

2. Similar Pronunciation

In natural English, both words often sound alike, especially when people speak quickly.

Example:

• Better than before.
• Finish, then leave.

3. Fast Typing

When typing emails, assignments, or text messages, many people hit the wrong vowel without noticing.

Incorrect:

I would rather stay home then go outside.

Correct:

I would rather stay home than go outside.

4. Grammar Confusion

Many learners know both words are common but forget which one belongs to comparisons and which one belongs to time.

For example:

❌ She is smarter then me.

✅ She is smarter than me.

❌ Eat dinner than go to bed.

✅ Eat dinner then go to bed.

5. Autocorrect Doesn’t Always Help

Because both words are correctly spelled English words, spell checkers often miss the mistake. Only careful proofreading can catch it.

Easy Trick to Remember Then or Than

You never have to confuse these words again if you remember these simple tricks.

Trick 1: Than = Compare

Both than and compare contain the letter A.

A = Comparison

Example:

• Faster than
• Bigger than
• More expensive than

Whenever you compare two things, choose than.

Trick 2: Then = Time

Then contains the letter E.

Think:

E = Event

or

E = Next Event

Example:

• First breakfast, then work.
• Finish reading, then sleep.

If something happens next, use then.

Trick 3: Ask Yourself One Question

Before writing the word, ask:

Am I comparing two things?

✔ Yes → than

❌ No → then

Examples:

• My house is larger than yours.
• We packed our bags, then left for the airport.

The Origin of Then or Than

Although then and than look alike today, they developed different meanings over hundreds of years.

Origin of Then

The word then comes from Old English “þonne”, meaning at that time, afterward, or next. It was used to describe time, sequence, and events.

Examples from history include expressions meaning:

• at that time
• after that
• next

Its meaning has stayed almost the same for centuries.

Origin of Than

The word than also comes from Old English “þonne.” In early English, the same word was often used for both time and comparison.

As English evolved during the Middle English period, writers gradually separated the meanings:

• than became the standard word for comparisons.
• then remained the word for time and sequence.

This spelling distinction made English easier to read and understand.

Why the Difference Exists Today

Modern English keeps these spellings separate because they perform different grammatical functions.

• Than introduces comparisons.
• Then refers to time or what happens next.

Although they share the same historical roots, centuries of language change gave each word its own role.

Their similar origin also explains why they still look and sound alike today.
