Then vs. than: What’s the difference? (2024)

Beware of exceptions

There is one exception to using the word than, which stems from its Old English and West Germanic roots. Nearly 417 years ago, it was common to use than in place of “when” “when as,” or even “then” in parts of speech. Anyone who reads historical literature, such as Shakespeare, encounters this nuisance frequently. Let’s take a look at an example,

“…go to, no more; lest it be rather thought you affect/ a sorrow than have it.”
– All’s Well That Ends Well, 1.1.48-49

What is the definition of then?

We use then to replace phrases that describe an event taking place in the past or at another time. In contrast, we also use then to replace “so,” “thus,” or “from then on,” or “hence,” so it’s easy to see how learning the difference between than and then can be difficult.

First, we used electric lightbulbs, then telephones, and then computers.

Another way of using then in its adverb form is to use it in place of “in addition” or “besides.” As shown below,

Then, there’s the outstanding balance she owes to the state of California.

The adverb form of then is also used as a consequential term, meaning an action that follows “then” in a sentence is the consequence of what occurred before “then.”

If you’re going to be late, then I’m not going to make appointments with you.

It is also common to use then as a way of finishing a statement where there is an agreement between the speaker and their statement.

We will meet at 5 p.m. then.

Synonyms of then as an adverb:

Words that are synonymous with then as an adverb include,

Additionally, again, also, besides, either, further, furthermore, likewise, more, moreover, too, withal, and yet.

Phrases such as “for good measure,” “in addition to,” “on top of,” “to boot, or “what’s more,” are also synonymous with then in its adverb form.

As a noun, then is used to reference the beginning of a period of time that occurred in the past. For example,

Since then, she started locking her car doors.

Then as an adjective

When used an adjective, then describes a past state of being or a former title held by a person, place, or thing. For example,

When used as a preposition, the word than indicates a comparison between two subjects in a sentence. The following subject mentioned after than is the primary point of comparison or the standard to which the first subject is being compared to. For example,

Amy is more different than me.

Than as a conjunction

As a term of conjunction, than is used synonymously “rather than” or “other than” is used with comparative adverbs and adjectives to provide an exception or contrast. For example,

They blame others rather than taking responsibility.
