Midterm or mid-term can both appear in English, but American writers normally use midterm as one word. The hyphenated mid-term is also documented as an alternative form, and it is especially associated with British English and some house styles.
For US readers, the safest everyday choice is simple: write midterm when you mean an exam, the middle of a term, or something occurring around the middle of a term.
For example:
I have a chemistry midterm next Tuesday.
The two forms do not represent two different words with different basic meanings.
Quick Answer
Midterm is the standard choice for most US English writing.
Mid-term is a recognized alternative spelling. Collins notes that British English usually uses the hyphenated form, while its American English entry uses midterm.
The simple US rule
- US English: midterm
- British English: mid-term may be preferred
- Meaning: essentially the same
- Plural in US English: midterms
- Common US examples: midterm exam, midterm grade, midterm elections
So, if you are writing for an American audience, choose midterm unless a specific publication or organization requires a different house style.
Why People Confuse Them
The confusion comes from the way English compounds develop.
The word combines mid- with term. English uses several patterns for compounds: some become one word, some stay open, and some keep a hyphen.
That makes midterm and mid-term look like competing rules.
Dictionary sources show that both forms exist. Wiktionary lists mid-term as an alternative form of midterm, while Collins identifies mid-term as the usual British form.
There is also a separate issue with other words beginning with mid-. For example, American writing commonly uses forms such as mid-July and mid-Atlantic. That does not mean midterm should normally be written with a hyphen.
Key Differences At A Glance
| Context | Best Choice | Why |
|---|---|---|
| US school exam | midterm | Common American form |
| US college course | midterm | Standard closed spelling |
| US political usage | midterm | Common US form |
| British English | mid-term may be preferred | British usage often favors the hyphen |
| General US writing | midterm | Clear and widely accepted |
| Specific house style | Follow the style guide | Publications can set their own conventions |
The key difference is therefore mainly spelling preference and regional or house style, not meaning.
Extra comparison:
- midterm — closed form; the normal choice for US English.
- mid-term — hyphenated alternative; especially associated with British usage and some style choices.
Are They the Same Word?
Yes. Midterm and mid-term refer to the same basic word and concept.
Both can describe something that occurs around the middle of a term. They can also refer to an examination given around the middle of an academic term.
For example, these sentences express the same basic idea:
- I have a midterm tomorrow.
- I have a mid-term tomorrow.
The first is the more natural choice for a US audience.
The spelling difference does not normally create a difference in meaning. Instead, the choice reflects regional usage, editorial preference, or house style.
US vs UK Preference
In US English, midterm is the preferred everyday spelling.
Cambridge’s American Dictionary uses midterm for both the adjective and the noun. Dictionary.com also labels midterm as American and gives examples such as midterm recess and midterm elections.
British usage is more mixed across sources, but Collins specifically notes that British English usually uses mid-term.
This means you should not treat mid-term as an impossible spelling. It is a documented form. The better practical rule is to match the variety of English and the style guide you are following.
For American websites, school papers, workplace documents, and general writing, midterm is the natural default.
Which Spelling Should You Use?
If you are writing for readers in the United States, use midterm.
Use midterm in common US phrases
- midterm exam
- midterm grade
- midterm review
- midterm results
- midterm elections
- midterm break
Examples:
The professor posted our midterm grades yesterday.
I need to study for my midterm exam tonight.
The class has a midterm review on Friday.
A particular publication may have its own preference. If its style guide specifies mid-term, follow that guide consistently.
For normal American writing, however, there is usually no need to add the hyphen.
When One Spelling Looks Wrong
Mid-term may look unusual to an American reader because midterm is the familiar US form.
For example:
I studied all weekend for my mid-term.
This is understandable, but midterm is the more natural US spelling:
I studied all weekend for my midterm.
A US institutional style guide from Indiana University of Pennsylvania specifically lists midterm as the correct style for the word.
At the same time, calling mid-term simply “wrong” would be too broad. Reputable dictionaries document it as an alternative or regional form.
The important distinction is between US preference and absolute correctness.
Common Mistakes (and Quick Fixes)
Mistake 1: Using a space
Wrong for the standard compound: mid term
Better: midterm
We have a midterm next week.
Mistake 2: Assuming the hyphen is always required
The presence of mid- does not mean every word beginning with it must retain a hyphen.
Better: midterm exam
Mistake 3: Calling every hyphenated form incorrect
Mid-term is a documented alternative form. It can appear in British English or in a particular house style.
Mistake 4: Mixing styles in one document
If you choose midterm, use it consistently throughout a US-focused document unless a quoted title or required style calls for another form.
Mistake 5: Confusing related hyphenation rules
Words beginning with mid- can have different treatments depending on what follows them. For example, mid-July follows a different pattern from the established compound midterm.
Everyday Examples
Here are natural examples for US English:
- My biology midterm is on Thursday.
- She studied for three hours before her midterm.

- He was worried about his upcoming midterm.
- The school offers a midterm break.
- The report included a midterm assessment of the project.
- The class met after the midterm to discuss progress.
- The midterm elections receive extensive news coverage.
In each example, midterm works naturally for US readers.
Dictionary-Style Word Details
Verb

Synonyms

There is no meaningful synonym difference created by the hyphen.
Example Sentences
- midterm: The professor moved the midterm to Wednesday.
