Memory Tricks to Never Get It Wrong Again

These simple techniques work instantly and stick in your memory:

Trick 1: The Vowel Trick

Then contains the letter E, just like time and sequence. If you are writing about time, use then.

Than contains the letter A, just like compare and grade. If you are comparing, use than.

Trick 2: The Substitution Test

Replace the word with ‘at that time.’ If the sentence still makes sense, use then.

Example: ‘We ate and [at that time] went home.’ Yes, this works. Use then.

Example: ‘She is taller [at that time] me. No, this does not work. Use than.

Trick 3: Ask ‘Am I Comparing?’

If you are setting two things against each other, you need than. If no comparison is happening, you almost certainly need then.

Trick 4: The ‘Time’ Acronym

Then = Time Both words start with THE ‘Then’ has an E for events in chronological order. Than has an A because you use it when contrasting item A against item B.

Pronunciation Why This Pair Gets Confused

Then and than are pronounced very similarly in fast or casual speech many native speakers reduce both words to a schwa sound (like ‘thun’), which makes them nearly indistinguishable when spoken.

Word	Standard Pronunciation	Common Reduced Form in Speech
Then	/ðɛn/ — short ‘e’ as in ‘pen’	Often sounds like ‘thun’
Than	/ðæn/ — short ‘a’ as in ‘pan’	Often sounds like ‘thun’

Because the spoken forms blur together it is essential to train yourself to check these words carefully when writing the sound alone is not a reliable guide.

Formal Writing vs Informal Speech Does the Rule Change

No The core rule does not change between formal and informal contexts. However, two nuances are worth knowing:

Pronoun case after ‘than

In formal writing, using ‘I,’ ‘she,’ or ‘he’ after ‘than’ is grammatically cleaner because it signals an implied verb. ‘She is faster than I [am].’ In casual speech, ‘She is faster than me’ is universally accepted and natural.

Contractions and shortening:

‘Then’ is sometimes omitted in very casual writing (‘We ate and went home’), but ‘than’ is rarely omitted because the comparison would become unclear without it. In academic or professional writing, always include both words.
