Quick Answer: Long Term vs Long-Term
Here’s the short answer:
| Usage | Correct Form | Example |
|---|---|---|
| As a compound adjective before a noun | Long-term | A long-term strategy |
| As a noun phrase or expression | Long term | In the long term, costs decrease |
| After the noun in many cases | Long term | The plan is long term |
Most modern dictionaries and style guides treat long-term as a hyphenated adjective and long term as a noun phrase. (Merriam-Webster)
What Does Long Term Mean?
The phrase long term refers to an extended period of time in the future.
It functions primarily as a noun phrase and commonly appears in expressions such as:
- In the long term
- For the long term
- Over the long term
Examples of Long Term
- Investing for the long term usually reduces risk.
- The company is thinking about the long term.
- These changes may help in the long term.
In these examples, the phrase refers to a future period rather than describing another noun. That’s why no hyphen is needed.
Common Expressions Using Long Term
Some frequently used phrases include:
- In the long term
- For the long term
- Over the long term
- Thinking long term
These expressions are widely accepted in professional, academic, and everyday English.
What Does Long-Term Mean?
Long-term is a compound adjective.
A compound adjective occurs when two or more words work together to describe a noun. In English grammar, compound adjectives that appear before a noun are often hyphenated for clarity.
Examples of Long-Term
- We need a long-term solution.
- She has a long-term investment plan.
- The company follows a long-term growth strategy.
- Scientists are studying the long-term effects of the treatment.
In each example, “long-term” directly modifies a noun.
Why the Hyphen Matters
Consider these sentences:
- We need a long-term plan.
- We need a long term plan.
While readers may understand both, the hyphen clearly signals that “long-term” works as one adjective describing “plan.” Style guides generally recommend the hyphenated version in this situation. (Merriam-Webster)
The Grammar Rule Behind Long Term vs Long-Term
Understanding the grammar rule makes this topic much easier.
Use Long-Term Before a Noun
When the phrase modifies a noun directly, use a hyphen.
Examples:
- Long-term goals
- Long-term planning
- Long-term relationships
- Long-term care
- Long-term success
The hyphen helps readers recognize that the words function together as a single modifier. (Merriam-Webster)
Use Long Term as a Noun Phrase
When you’re referring to an extended future period, don’t use a hyphen.
Examples:
- Think about the long term.
- In the long term, profits may rise.
- The project is beneficial for the long term.
After the Noun
English style guides often remove hyphens when the compound adjective appears after the noun.
Examples:
- Their strategy is long term.
- The impact will be long term.
Although some publishers keep the hyphen for consistency, the open form is common in this position. (Merriam-Webster)
Real-Life Example: How a Marketing Team Fixed a Costly Writing Mistake
A mid-sized digital marketing agency was preparing a series of reports for a major client. The reports focused heavily on growth forecasting, investment planning, and customer retention strategies.
Throughout the documents, different team members used varying forms of the phrase. Some wrote “long term strategy,” others used “long-term strategy,” and a few switched between the two without any pattern.
During the client’s review process, the inconsistency was noticed by the company’s editorial department. While the mistake wasn’t severe enough to affect the project’s outcome, it raised concerns about attention to detail and editorial standards.
The agency decided to create an internal style guide. The rule was simple:
- Use long-term when describing a noun.
- Use long term when referring to a period of time.
After implementing the guideline, the company improved consistency across blog posts, white papers, case studies, and client reports.
The lesson is straightforward: grammar mistakes may seem minor, but consistent writing strengthens professionalism, credibility, and trust. In industries where communication matters, small details can influence how readers perceive expertise.
