More Then or More Than: Which Is Correct?

Few mix-ups are as common, or as quietly persistent, as writing more then when you mean more than. The correct phrase is more than, the everyday way English compares amounts and degrees: "she earns more than he does," "it took more than an hour," "more than anything, I wanted to leave." The word doing the work is than, the comparison word that links the two things being measured. Then, by contrast, is a word about time and sequence, it means next or at that time, as in "we finished dinner, then watched a film." The two are spelled almost identically and sound nearly the same when spoken quickly, which is exactly why more then slips so easily off the keyboard. But in the fixed phrase that means a greater amount, the correct spelling is always more than, never more then. This puts the pair among the most frequent commonly confused words, where a single vowel separates the right word from the wrong one. This guide explains what each word does, why the confusion is so widespread, and a one-letter trick that settles it for good.

Which One Is Correct?

For comparisons, more than is the only correct spelling, and more then is a misspelling. Any time you are saying that one amount, number, or degree is greater than another, the word you need is than: "more than fifty people," "more than ever," "more than enough." Writing more then in these sentences is an error, the equivalent of swapping in a sound-alike word that means something else entirely.

The reason comes down to what each word does. Than is a conjunction used in comparisons; it is the standard partner of comparative words like more, less, bigger, fewer, rather, and other. Then is an adverb of time and sequence, meaning at that point or next. They are not interchangeable, because comparison and time are different jobs. More sets up a comparison, so it calls for the comparison word, than.

The catch is that more then is not always flagged as wrong by spell-checkers, because in rare sentences then can legitimately follow more as a separate time word ("we needed more, then we left"). That technicality lets the misspelling slip through software unnoticed. But as the single fixed phrase meaning a greater quantity, it is always more than. The fix is to recognize that you are comparing, and to reach for than every time you do.

What Each Word Means

Sorting than from then is the whole battle, because once you know which job each word does, the choice after more is obvious.

Than is the comparison word. Its only role is to connect two things being measured against each other, showing that one exceeds, falls short of, or differs from the other. It appears after comparative terms: more than, less than, taller than, better than, rather than, other than. In every case it answers the question "compared to what?" In "she is older than her brother," than links older to her brother. In "more than I expected," it links more to I expected. If your sentence is weighing one thing against another, than is the word.

Then is the time-and-sequence word. It means at that time ("I was younger then"), next ("we ate, then we slept"), or in that case ("if you're tired, then rest"). Its job is to place events in order or at a point in time, never to compare amounts. You could not swap it into a comparison: "she is older then her brother" makes no sense, because no sequence of events is being described.

So the two words live in separate worlds. Than belongs to comparison; then belongs to time. More is a comparative word, it sets up a measurement of one amount against another, so the word that follows it in the fixed phrase is always than. The presence of more is your signal that a comparison is happening, and comparisons take than.

Why People Mix Them Up

If than and then do such different jobs, why is more then one of the most common errors in written English? The confusion is almost entirely about sound, with a little help from how often both words appear.

The first and biggest cause is pronunciation. In ordinary speech, the vowels in than and then both collapse into a quick, neutral uh sound. "More than ten" and the misspelled "more then ten" come out of the mouth identically. Because the ear cannot hear a difference, writers spell the phrase the way it sounds, and they default to then, the more common everyday word. There is no audible cue to correct them, so the error feels right.

The second cause is that then is simply the more frequent and more familiar of the two words in casual writing, used constantly to string events together. When the fingers are typing fast, the brain supplies the high-frequency then by reflex, even when comparison is the intended meaning. Familiarity wins over precision.

A third factor is that spell-checkers usually let more then pass. Both words are correctly spelled in isolation, and there exist rare sentences where more then is valid, so the software cannot reliably flag the phrase as an error. Writers who rely on the red underline to catch mistakes get no warning here. The combined effect, identical sound, a more familiar wrong word, and no software safety net, is what makes more then so stubbornly common. The cure is conceptual: learn that comparisons take than, and the more then habit disappears.

Examples in Sentences

Seeing more than used correctly, beside the more then error, makes the right choice stick.

Correct uses of more than (comparison):

• The trip cost more than we had saved.
• She read more than thirty books last year.
• More than anything, he wanted to be heard.
• It will take more than good intentions to fix this.

Correct uses of then (time / sequence):

• We finished the report, then went home.
• I was a student then, with no money to spare.
• If the light is red, then stop.

Wrong → right corrections:

• She has more then enough. → She has more than enough.
• It costs more then I thought. → It costs more than I thought.
• More then a hundred guests came. → More than a hundred guests came.

Notice that in every corrected sentence, a comparison is being made, one amount set against another, so than is required. The then sentences, by contrast, all describe time or order, which is the only place then belongs.

More Than vs More Then: Side by Side

The table lays the comparison word and the time word next to each other so the difference is unmistakable.

Aspect	Than (more than)	Then (more then)
Part of speech	Comparison conjunction	Time / sequence adverb
Job	Compares two things	Marks order or a point in time
Key letter	a (compare)	e (when)
Pairs with	more, less, taller, rather	next, after that, at that time
Correct after "more"?	Yes, always	No (except rare separate clause)
Example	"more than ten"	"we ate, then left"

The takeaway sits in the "key letter" row: comparisons take than with an a. Because more always sets up a comparison, the correct phrase is always more than.

How to Remember

The simplest trick links the spelling to the meaning by a single shared letter. Than and compare are connected by the letter a: when you compare amounts, you use than. Then and time (and when) share the letter e and the idea of sequence: then is about when. So when you write more, ask yourself, am I comparing? If yes, and after more the answer is always yes, use than with an a.

A second test is to try swapping in next or at that time. If the sentence still makes sense, then is right ("we ate, next we left" works). If it turns to nonsense, "she has more next enough", you need than. Since more always introduces a comparison, this test confirms than every time. Hold on to the a in than and compare, and more then stops happening.

Related Spelling Mixups

More then vs more than belongs to a group of errors driven by sound-alike words and small spelling slips. If this pair caught you, two related cases are worth reviewing. The first is perfer vs prefer, where the right form depends on getting the letters of a short, common word in the correct order. The second is ect vs etc, another high-frequency abbreviation that people misspell from habit and speech. Each, like more than, is a case where the correct version is fixed and the wrong version simply reflects how the phrase sounds or feels in a hurry, so a small, deliberate rule fixes it for good.

Conclusion

The phrase that means a greater amount is more than, always spelled with than, the comparison word. More then is a misspelling that swaps in then, the word for time and sequence, and although the two sound nearly identical in speech, they do completely different jobs: than compares one thing with another, while then places events in order or at a point in time. Because more sets up a comparison, the word that follows it in the fixed phrase is always than, never then. The confusion survives because the words sound the same, because then is the more familiar word, and because spell-checkers rarely flag the error, but the cure is a single letter: than and compare both carry an a, so any comparison takes than. Tie that a to the act of comparing, and you will write more than correctly every time.
