Long Term vs Long-Term can confuse English learners, students, and experienced writers because the words look identical, but their grammatical roles differ in writing.
When reviewing writing, I often notice the same mix-up after someone has typed a phrase, trusted autocorrect, or copied a coworker’s report without checking the hyphenated form or open form. The small hyphen may seem minor, yet it can affect the grammatical roles of the phrase and the sentence. The basic rule becomes easier when you focus on grammar, sentence structure, grammatical context, and spelling rather than trying to memorize every example.
The long-term hyphenated form works as a modifier before a noun, while long term stays open when the form functions differently in the sentence. Learning these different ways to use the forms helps writers avoid common mistakes and second-guess less often. In formal contexts, professional writing, and everyday communication, choosing the correct form improves writing accuracy and makes your message clearer, accurate, and natural. The same grammatical distinction applies in informal contexts, although the tone may be more simple and conversational.
A useful pattern is to understand the simple difference instead of memorizing isolated examples. The confusion becomes easier to handle when you remember that long-term is the hyphenated choice when the phrase acts as a combined modifier, while long term remains open when the grammatical structure requires it. This approach makes the spelling easier to remember and gives professionals, everyday writers, and English learners a practical way to improve communication with greater accuracy.
Long Term vs Long-Term: The Quick Answer
The difference between long term and long-term depends mainly on grammatical function.
| Form | Main function | Example |
| long term | Noun phrase or adverbial expression | “Think about the long term.” |
| long-term | Compound adjective | “We need a long-term strategy.” |
| longterm | Generally nonstandard spelling | “We need a longterm strategy.” |
When long-term appears directly before a noun and describes that noun, the hyphen usually makes the relationship clear.
Consider:
“The company needs a long-term strategy.”
Here, long-term describes “strategy.” The two words function together as one compound modifier.
Now look at this sentence:
“The strategy should benefit the company in the long term.”
Here, long term identifies a period of time. It doesn’t directly modify a noun, so the hyphen isn’t needed.
This distinction appears in thousands of everyday expressions:
- long-term goal
- long-term plan
- long-term effects
- long-term investment
- in the long term
- over the long term
- for the long term
- think long term
The form changes because the grammatical job changes.
What Does Long Term Mean?
Long term refers to an extended period of time. It doesn’t have one universal duration because the meaning depends on the subject and context.
For a business, the long term might mean several years. For a person’s career, it could mean decades. In a scientific study, researchers might define a long-term period using a specific number of months or years.
The important point is that long term identifies a period rather than directly modifying another noun as a compound adjective.
For example:
- “What will happen in the long term?”
- “We need to think about the long term.”
- “The changes could save money over the long term.”
- “They are planning for the long term.”
In each example, term remains a noun. The word long describes the type or duration of that term.
Think of it like the short term and the long term. Both phrases refer to periods rather than acting as adjectives directly attached to another noun.
When to Use Long Term Without a Hyphen
Use long term without a hyphen when the expression functions as a noun phrase or an adverbial expression.
One of the most common constructions is in the long term.
For example:
“The initial cost is high, but the equipment should save money in the long term.”
Here, “the long term” means an extended future period.
Other common constructions include:
- in the long term
- over the long term
- for the long term
- from the long-term perspective — note that the adjective is hyphenated here because it modifies “perspective”
- think long term
- plan long term
- work long term
The phrase can also appear after certain verbs:
“We need to think long term.”
In this sentence, long term describes how the person should think. It isn’t directly modifying a noun.
Another example:
“The new policy may work well long term.”
Here, long term has an adverbial role. It tells you the time frame in which the policy may work.
“In the Long Term” vs “In the Long-Term”
This is one of the most common points of confusion.
The standard expression is:
in the long term
Not:
in the long-term
Why? Because the long term is a noun phrase. The word “term” remains the noun, while “long” describes it.
Compare these sentences:
- “The change will help in the long term.”
- “The company needs a long-term strategy.”
The first sentence refers to a period of time. The second uses long-term as a compound adjective modifying “strategy.”
A simple way to remember this distinction is to look at the word immediately following the phrase.
In the long term contains the article “the” and refers to the period itself.
Long-term strategy places the compound directly before the noun it modifies.
What Does Long-Term Mean?
Long-term is a compound adjective. It describes something that lasts for an extended period, relates to an extended period, or is intended to continue for an extended period.
For example:
- long-term planning
- long-term growth
- long-term effects
- long-term care
- long-term investment
- long-term relationship
- long-term agreement
- long-term strategy
The hyphen connects long and term because they work together to modify the following noun.
Consider:
“The business created a long-term growth plan.”
The phrase long-term describes “growth plan.” Without the hyphen, the reader could momentarily interpret the words differently.
The same pattern appears in many English compounds:
- high-quality product
- well-known author
- full-time employee
- short-term loan
- long-term contract
The hyphen acts like a small grammatical bridge between the words.
When to Hyphenate Long-Term
Use long-term when it functions as a compound adjective, especially when it appears immediately before a noun.
Here are some common examples:
| Long-term expression | What it describes |
| long-term plan | A plan intended for an extended period |
| long-term goal | A goal expected to take substantial time |
| long-term investment | An investment held or considered over an extended period |
| long-term effects | Effects that continue or appear over an extended period |
| long-term strategy | A strategy designed for sustained use |
| long-term relationship | A relationship lasting for an extended period |
| long-term care | Care provided over an extended period |
| long-term agreement | An agreement lasting for an extended period |
For example:
“The team developed a long-term strategy for reducing operating costs.”
Here, long-term tells the reader what kind of strategy the team developed.
Another example:
“Researchers examined the long-term effects of the treatment.”
Again, long-term directly modifies “effects.”
The same rule works in professional writing:
“Our company needs a long-term solution rather than a temporary fix.”
The phrase long-term solution is standard because the compound adjective comes directly before the noun.
Why the Hyphen Matters in Long-Term
A hyphen can make the relationship between words easier to understand.
Take this phrase:
long-term investment
The hyphen tells the reader that long and term belong together as one modifier.
Without the hyphen:
long term investment
the meaning may still be obvious, especially in casual writing. However, standard edited US English generally prefers long-term investment when the phrase functions as a compound adjective before the noun.
Hyphens often work as tiny road signs for readers. They tell you which words belong together.
For example:
“a high-quality product”
The phrase doesn’t mean a product that is “high” and separately “quality.” The two words combine to describe the product.
Likewise:
“a long-term investment”
The two words work together to describe the investment.
Long Term as a Noun Phrase
One of the easiest ways to understand the difference is to treat the long term as a noun phrase.
For example:
“The company is thinking about the long term.”
What is the company thinking about? The long term.
That phrase names an extended period.
You can replace it conceptually with another noun phrase:
“The company is thinking about the future.”
Both phrases identify a period or time frame.
Common examples include:
- “The long term matters more than a quick gain.”
- “Consider the long term before making a decision.”
- “The policy could create problems in the long term.”
- “They are investing for the long term.”
- “The benefits become clearer over the long term.”
In these sentences, term remains a noun. That’s why you don’t need a hyphen between “long” and “term.”
Long Term as an Adverbial Expression
Modern English also uses long term adverbially.
For example:
“Will this approach work long term?”
Here, long term explains the time frame in which the approach will work.
You could also write:
“Will this approach work in the long term?”
Both constructions communicate a similar idea. The second is more explicit because in the long term clearly identifies the time period.
Other examples include:
- “The changes should help long term.”
- “We need to think long term.”
- “The company plans to grow long term.”
- “This decision could hurt the business long term.”
In formal writing, in the long term or over the long term can sometimes provide a clearer and more traditional construction.
However, long term as an adverbial expression is common in contemporary English, especially in business and conversational writing.
Longterm: Is It One Word?
Longterm is generally not the standard spelling in US English.
The standard choices are:
- long term
- long-term
Which one you choose depends on the grammatical function.
For example:
- “We need a longterm plan.”
- “We need a long-term plan.”
And:
- “It may help longterm.”
- “It may help long term.”
You may encounter longterm online because people often combine words while typing quickly. Digital communication also encourages informal spellings, abbreviations, and shortcuts.
However, frequency on the internet doesn’t automatically make a form standard.
If you’re writing an article, resume, report, business proposal, academic paper, or professional email, stick with long term or long-term.
Long Term vs Long-Term Grammar Rules
The central rule becomes easier when you focus on grammatical function rather than memorizing isolated examples.
Before a Noun: Usually Long-Term
When long-term directly modifies a noun, use the hyphen.
Examples:
- long-term objective
- long-term contract
- long-term planning
- long-term consequences
- long-term customer
- long-term commitment
Sentence:
“The company signed a long-term contract with its supplier.”
The phrase describes what kind of contract the company signed.
Referring to the Period: Long Term
When you mean the extended period itself, use long term.
Examples:
- “The decision may cost more in the long term.”
- “Think about the long term.”
- “They are preparing for the long term.”
Here, “term” acts as the noun.
After a Linking Verb
This area requires a little more care because the simple rule “hyphenate only before a noun” isn’t enough for every construction.
Consider:
“The effects are long-term.”
Here, long-term still functions as an adjective describing the effects.
Compare it with:
“The effects will become clearer in the long term.”
The second sentence uses the long term as a noun phrase.
So the better rule is to ask what grammatical function the phrase has rather than relying only on its position.
Long Term vs Long-Term Examples
Seeing the forms side by side makes the distinction much easier.
| Long-term | Long term |
| We need a long-term plan. | We need to think about the long term. |
| She has a long-term goal. | Her decision will matter in the long term. |
| They made a long-term investment. | The investment should pay off over the long term. |
| The study examined long-term effects. | The effects may become clearer in the long term. |
| We need a long-term solution. | This approach could work long term. |
| They signed a long-term agreement. | They are planning for the long term. |
Notice the pattern. Long-term usually sits next to a noun as a compound modifier. Long term commonly appears as a noun phrase or adverbial expression.
Long Term vs Long-Term in Professional Writing
Professional writing benefits from precise hyphenation because readers often scan documents quickly.
Consider a business report:
“The company needs a long term growth strategy.”
A polished version would be:
“The company needs a long-term growth strategy.”
Now compare:
“The company expects the investment to produce results in the long term.”
No hyphen belongs in in the long term.
This distinction matters in several professional settings.
Business Writing
Common expressions include:
- long-term strategy
- long-term growth
- long-term planning
- long-term profitability
- long-term partnership
- long-term objectives
Example:
“The board approved a long-term strategy focused on sustainable growth.”
Financial Writing
Finance frequently uses both forms.
Examples:
- long-term investment
- long-term debt
- long-term savings
- long-term financial planning
- “Investing for the long term”
- “The returns may improve over the long term.”
The distinction remains grammatical rather than financial.
Academic Writing
Academic papers often discuss long-term effects, long-term trends, and long-term outcomes.
For example:
“The researchers analyzed the long-term effects of the intervention.”
But:
“The results became more significant in the long term.”
The first uses a compound adjective. The second uses a noun phrase.
Workplace Emails
You might write:
“Let’s create a long-term plan for the project.”
But:
“We should consider how this decision affects the team in the long term.”
Both forms belong in professional communication. The sentence determines the spelling.

Long Term vs Long-Term in Everyday Conversation
Everyday speech often makes the distinction less noticeable because listeners don’t see the hyphen.
When someone says:
“We need to think long term.”
you hear the same basic words as in:
“We need a long-term plan.”
Writing exposes the difference.
For example:
Conversation:
“I think it’ll work long term.”
Written sentence:
“I think it will work long term.”
But:
“It could become a long-term solution.”
The meaning stays closely related. The grammatical role changes.
Long-Term vs Long Run
Long-term and long run often overlap in meaning, but they aren’t identical grammatical constructions.
For example:
“This could provide long-term benefits.”
You could express a similar idea as:
“This could provide benefits in the long run.”
The first uses long-term as an adjective.
The second uses the long run as a noun phrase.
Notice another important detail:
- long-term benefits
- in the long run
- long run benefits in standard compound-adjective usage
The expression in the long run follows its own established pattern. It doesn’t normally become in the long-run.
You can use either expression depending on the sentence and intended tone.
Long Term vs Long-Term vs Longterm
The three forms are easy to compare.
| Form | Standard US English | Typical role | Example |
| long term | Yes | Noun phrase/adverbial expression | “Think about the long term.” |
| long-term | Yes | Compound adjective | “A long-term goal takes patience.” |
| longterm | Generally no | Nonstandard spelling | “a longterm goal” |
A useful memory trick is:
Hyphen = combined modifier.
If long and term combine to describe a noun, write long-term.
If you’re talking about the period itself, write long term.
Common Mistakes With Long Term and Long-Term
Mistake: Writing “In the Long-Term”
A common error is:
“The decision will help in the long-term.”
The standard form is:
“The decision will help in the long term.”
The phrase contains the long term, which functions as a noun phrase.
Mistake: Writing “Longterm”
Another frequent mistake is combining the words into one.
“We need a longterm strategy.”
Use:
“We need a long-term strategy.”
Mistake: Removing the Hyphen Before a Noun
Another error looks like this:
“We need a long term strategy.”
The standard edited form is:
“We need a long-term strategy.”
The hyphen connects the compound modifier.
Mistake: Hyphenating Every Use
Some writers learn that long-term is correct and then use it everywhere.
That creates sentences such as:
“We need to think long-term about the problem.”
In this construction, think long term is generally written without the hyphen.
A cleaner version is:
“We need to think long term about the problem.”
Or, in a more explicit construction:
“We need to think about the problem in the long term.”
Mistake: Treating “Long Term” as One Fixed Spelling
The biggest misconception is assuming that one form must always be correct.
English doesn’t work that way here.
The same two words can take different forms because their grammatical roles differ.
How to Know Whether You Need a Hyphen
You can use a simple three-step test when editing.
Ask What the Phrase Modifies
Look at the words immediately after long term.
If the phrase directly describes a noun, long-term is usually appropriate.
long-term strategy
long-term effects
long-term agreement
If you’re referring to the time period itself, use long term.
in the long term
over the long term
for the long term
Try the “The” Test
If the natural phrase contains the, you’re often dealing with the noun phrase the long term.
For example:
“the long term”
“in the long term”
“for the long term”
These don’t need a hyphen.
However:
“a long-term strategy”
doesn’t use “the” between the words because long-term acts as one compound adjective.
Look for the Noun
Ask yourself:
What noun is “long-term” describing?
In:
“a long-term investment”
the answer is “investment.”
In:
“long-term effects”
the answer is “effects.”
If no noun follows because you’re talking about the period itself, long term may be the correct choice.
A Practical Editing Checklist
Before you publish or submit a sentence, run through this quick checklist:
- Is term acting as a noun?
- Does long-term directly modify a noun?
- Am I using the phrase in the long term?
- Am I using over the long term?
- Am I using for the long term?
- Did I accidentally write longterm as one word?
- Would the sentence sound clearer with in the long term instead of long term?
These questions take only a few seconds.
For example:
“We need a long term solution.”
Ask: What does the phrase describe?
Answer: solution.
Correction:
“We need a long-term solution.”
Now consider:
“This decision could help in the long-term.”
Ask: Is “the long term” the time period?
Yes.
Correction:
“This decision could help in the long term.”
A Real-World Editing Example
Imagine a manager writing a project update:
“Our short term goal is to reduce costs, but we need a long term strategy that works long-term.”
The sentence contains several opportunities for correction.
A polished version would be:
“Our short-term goal is to reduce costs, but we need a long-term strategy that works long term.”
Why?
- short-term goal = compound adjective
- long-term strategy = compound adjective
- works long term = adverbial expression
The sentence becomes much easier to read once each phrase matches its grammatical function.
Long Term vs Long-Term in Resumes and Cover Letters
Professional documents often contain phrases such as long-term goals, long-term career plans, and long-term development.
For example:
“My long-term career goal is to lead a product development team.”
Here, long-term directly modifies “career goal.”
Another example:
“I am interested in building skills that will remain valuable in the long term.”
Here, the long term refers to the future period.
Both forms are useful in career writing.
The same principle applies to resumes:
- long-term project
- long-term client
- long-term strategy
- long-term professional goal
But:
“This experience will benefit my career in the long term.”
No hyphen is needed in the final phrase.
Long Term vs Long-Term in Academic Writing
Academic writing often requires careful distinction because researchers describe both long-term phenomena and outcomes observed over the long term.
For example:
“The study investigated the long-term effects of sleep deprivation.”
Here, long-term modifies “effects.”
Another sentence might say:
“These differences became more noticeable over the long term.”
Here, over the long term identifies the period during which the differences became noticeable.
The distinction helps prevent ambiguity and keeps academic prose consistent.

| One-word spelling | longterm | Generally avoid it |
FAQs
1. Is it long term or long-term?
Both long term and long-term are correct. Use long-term when the phrase comes before a noun as a compound modifier, such as “a long-term plan.” Use long term when it functions as a noun phrase, such as “in the long term.”
2. Why does long-term need a hyphen?
The hyphen connects long and term when they work together to describe a noun. This hyphenated form makes the sentence structure clearer and shows that the two words act as one modifier.
3. Is “longterm” one word?
No. Longterm is generally an incorrect spelling in standard English. The accepted forms are long term and long-term, depending on the grammatical context.
4. Is long-term formal or informal?
Long-term can be used in both formal contexts and informal contexts. You will commonly see it in professional writing, reports, plans, business communication, and everyday sentences.
5. How can I remember the difference?
A simple pattern can help: when long and term come together before a noun as a modifier, use long-term. When the phrase stands on its own, use long term. This simple rule helps writers avoid common mistakes and improve writing accuracy.
Conclusion
Understanding Long Term vs Long-Term becomes much easier when you focus on the grammatical role of the phrase rather than the spelling alone. Use the hyphenated form, long-term, when the words work together before a noun, such as a long-term goal or long-term strategy. Use the open form, long term, when the phrase functions independently, such as in “in the long term.” Remember that longterm is not the standard form.
Once you recognize this simple difference, you can write with greater accuracy, clarity, and confidence. Whether you are an English learner, student, professional, or everyday writer, knowing when to use the hyphen helps your communication look more polished and makes your sentence structure easier to understand.
