Long Term or Long-Term: 7 Clear Rules for Better Writing

Confused Words

7 min read

Long term or long-term is a common English usage question. The two forms are closely related, but they do not normally serve the same grammatical function.

The simple rule is easy:

long-term is normally used before a noun as a compound adjective.
long term is normally used as a noun phrase when referring to an extended period.

For example:

We need a long-term plan.

But:

We are planning for the long term.

Both forms are standard. The hyphen depends on how the phrase functions in the sentence, not on American versus British spelling.

Cambridge lists long-term as an adjective meaning continuing far into the future, while its Business English entry also lists long term as a noun.

Quick Answer

Use long-term when the phrase directly describes a noun.

Example:

She has a long-term goal.

Use long term when the phrase refers to an extended period by itself.

Example:

She is planning for the long term.

A useful memory rule is:

Before a noun → usually long-term.

As a period of time → usually long term.

This distinction is supported by usage guidance from the Washington State Office of Financial Management and Cambridge Dictionary.

Why People Confuse Them

The confusion is understandable because the words have the same basic idea.

Both forms relate to something that continues or matters over an extended period. The only visible difference is the hyphen.

That small mark changes how the words work together.

Compare:

They made a long-term investment.

Here, long-term describes the noun investment.

Now compare:

They are investing for the long term.

Here, long term refers to the future period itself.

Because both sentences discuss the same general idea, writers often use the two forms interchangeably. In polished writing, however, the grammatical role should guide the choice.

Key Differences At A Glance

Context	Best Choice	Why
Before a noun	long-term	It works as a compound adjective
After “the”	long term	It functions as a noun phrase
“In the ___”	long term	It refers to a period
“A ___ plan”	long-term	It describes the plan
“For the ___”	long term	It names an extended period
“___ effects”	long-term	It modifies “effects”

Quick comparison:

long-term = descriptive form
long term = period of time
longterm = not the standard form in ordinary edited English

Are They the Same Word?

They are closely related forms built from the same two words, but their grammatical roles differ.

Long-term works as a compound adjective. It describes something that continues, exists, or has an effect over a long period.

The company needs a long-term strategy.

Long term is commonly used as a noun phrase.

The company is thinking about the long term.

So the difference is mainly about hyphenation and grammatical function, rather than a completely different meaning.

Cambridge’s entries support this distinction by listing long-term as an adjective and long term as a noun in Business English.

US vs UK Preference

There is no major US-versus-UK spelling difference here.

American and British English both use long-term as a compound adjective and long term in noun-phrase constructions.

For example, both varieties can use:

a long-term agreement

and:

planning for the long term

Cambridge gives long-term in both its US and UK dictionary information.

This means you should not treat the hyphen as an American spelling choice or a British spelling choice. It is primarily a matter of grammatical function and sentence structure.

Which Spelling Should You Use?

For American English, use the same basic rule:

Use long-term before a noun when the two words work together as one description.

Examples:

long-term plan
long-term goal
long-term contract
long-term investment
long-term solution
long-term effects

Use long term when you are referring to the period itself.

Examples:

in the long term
over the long term
for the long term
think about the long term

If you remember only one rule, remember this:

A noun follows? Use long-term. A period is being discussed? Use long term.

When One Spelling Looks Wrong

The wrong form often becomes obvious when you look at the word that follows.

Consider:

We need a long-term solution.

The phrase long-term directly describes solution, so the hyphen makes the relationship clear.

Now consider:

This decision will help us in the long term.

Here, long term does not directly describe another noun. It refers to a future period.

A common error is:

We need a long term solution.

In careful writing, long-term solution is preferable because the two words form a compound modifier before the noun.

Another common error is:

It will help us in the long-term.

The usual form is:

It will help us in the long term.

Common Mistakes

Mistake 1: Writing “long term” before a noun

Incorrect or less polished:

We need a long term strategy.

Better:

We need a long-term strategy.

Mistake 2: Adding the hyphen after “the”

Incorrect in the usual construction:

We are planning for the long-term.

Better:

We are planning for the long term.

Mistake 3: Writing “longterm”

Avoid:

longterm planning

Use:

long-term planning

The standard forms are long term and long-term, depending on function.

Mistake 4: Treating the hyphen as optional everywhere

The hyphen is not simply a decoration. It helps show that two words work together as a single modifier before a noun.

Everyday Examples

Here are natural examples for American English:

She has a long-term goal of buying a home.
We need a long-term solution to the problem.
The company signed a long-term contract.
They are making a long-term investment.
This decision may benefit the community in the long term.
We need to think about the long term.
The new policy could produce long-term effects.
He is saving money for the long term.
They developed a long-term plan for the business.
Small changes can make a difference over the long term.

Notice the pattern: when the phrase comes before and describes a noun, the hyphen is normally used. When the phrase refers to the period itself, it is normally open.

FAQs

Is long term or long-term correct?

Both forms are correct, but they are used differently. Use long-term when it works as a compound adjective before a noun and long term when it functions as a noun phrase.

Is long-term always hyphenated?

No. The hyphen is normally used when long-term functions as a compound adjective, especially before a noun. The phrase is usually written long term when it refers to a period of time by itself.

Should I write “in the long term” or “in the long-term”?

Write in the long term. Here, the phrase refers to an extended period and does not directly modify a following noun.

Is “long term” one word?

No. In standard English, it is either long term as two separate words or long-term with a hyphen when it functions as a compound adjective.

Is long-term used in American English?

Yes. Long-term is standard American English. Cambridge’s American Dictionary lists it as an adjective meaning continuing for many years or far into the future.

Which is correct: long-term goal or long term goal?

Long-term goal is the standard choice. The two words work together to describe the noun goal, so the hyphen helps connect them.

Is “longterm” correct?

Longterm is not the standard form for ordinary edited English. Use long-term when the phrase is a compound adjective and long term when it is used as a noun phrase.

Conclusion

The choice between long term or long-term is mainly about how the phrase functions in a sentence.

Use long-term when it directly describes a noun:

a long-term plan

Use long term when you refer to an extended period:

in the long term

The easiest rule is:

Before a noun → long-term.

As a period of time → long term.

Both forms are standard in American English, so you do not need to choose between them based on US or UK spelling. Instead, look at the sentence and decide whether the phrase is describing a noun or naming a period of time.
