You’re typing a sentence, you get to the word “long,” and you freeze. Is it long term? Long-term? Or can you just smash it together as longterm and move on with your day? If you’ve Googled this more than once, you’re not careless — you’re just running into one of those English rules that nobody actually teaches, even though it shows up constantly in resumes, business emails, and investment advice.
Here’s the short version: long term and long-term are both correct, depending on the job they’re doing in your sentence. Longterm, as one solid word, isn’t standard in edited English — no major dictionary or style guide treats it as the preferred spelling, even in 2026.
That one-line answer solves 80% of the confusion. The other 20% is knowing which form to reach for and why the “rule” sometimes seems to bend. Let’s get into it.
Long Term vs. Long-Term vs. Longterm: The Quick Breakdown
| Form | Grammatically standard? | What it does |
|---|---|---|
| long term | Yes | Acts as a noun phrase (a thing you’re referring to) |
| long-term | Yes | Acts as a compound adjective (describes a noun) |
| longterm | Not in standard usage | Occasionally used informally or as branding |
If you remember nothing else from this article, remember that table. Everything below is just explaining why it works this way, plus the tricky edge cases that trip people up even after they “know” the rule.
The Real Rule: It’s About the Job the Word Is Doing
The confusion isn’t really about spelling — it’s about grammar. “Long term” changes form depending on whether it’s acting as a noun or as an adjective.
- As a noun phrase, it stands alone: “We’re planning for the long term.” Here, “the long term” is a thing — a period of time you’re thinking about. No hyphen.
- As a compound adjective, it sits directly in front of another noun and describes it: “We need a long-term plan.” Here, “long-term” is doing one job together, modifying “plan.” Hyphen required.
Think of the hyphen as glue. When two words are working as a single descriptive unit right before a noun, the hyphen holds them together so the reader doesn’t have to pause and figure out the relationship themselves.
Why “Longterm” Isn’t the Answer
English does absorb some compound words over time — email, website, and online all used to carry hyphens or spaces before they merged into single words. That history is exactly why so many writers assume “longterm” is next in line.
It isn’t, at least not yet. AP Style and the Chicago Manual of Style both still call for “long-term” as a hyphenated adjective, and neither treats “longterm” as an accepted alternate the way some dictionaries now accept “longstanding” as a variant of “long-standing.” So while the compound-word trend is real, “long term” hasn’t followed it — and there’s no strong signal in current style guide updates that it’s about to.
You might spot “longterm” in social captions, marketing copy, or a product name someone chose for branding reasons. That’s a stylistic choice, not evidence that the spelling has become standard — the same way “thru” shows up on fast food signs without ever becoming preferred spelling for “through.”
The Exception Almost Everyone Misses: Linking Verbs
This is the part most grammar guides skip, and it’s where a lot of otherwise careful writers still get tripped up.
The “hyphenate before a noun” rule has a wrinkle: when “long term” follows a linking verb like “is,” “are,” “was,” or “seems,” it usually loses the hyphen — even though it’s still functioning adjectivally.
- “The plan is long term.” — no hyphen, because it follows “is” rather than sitting directly before the noun it modifies.
- “We need a long-term plan.” — hyphen, because it sits directly before “plan.”
Compare that to a phrase like “well-known”: you’d write “a well-known author” but many style guides also drop the hyphen in “the author is well known.” The logic is the same — hyphens in compound modifiers primarily exist to prevent misreading before a noun. After a linking verb, the risk of misreading mostly disappears, so several major guides relax the rule.
Not every style guide treats this identically, and some publications keep the hyphen after “is” for consistency. If you’re writing for a specific outlet or company style guide, that guide’s preference always wins — treat this as the general convention, not an absolute law.

Long Term or Long-Term: Real Sentence Examples
Seeing the rule applied is faster than memorizing it. Here’s how it plays out across a few common contexts.
Business and strategy:
- ✅ “The company released a long-term growth plan.”
- ✅ “Executives are focused on the long term.”
Finance:
- ✅ “She holds long-term investments in index funds.”
- ✅ “Long-term capital gains are taxed differently than short-term ones.”
- ✅ “Over the long term, diversified portfolios tend to recover from downturns.”
Health and relationships:
- ✅ “He’s managing a long-term health condition.”
- ✅ “They’ve been in a long-term relationship for six years.”
- ✅ “Doctors are more concerned about the long term than the immediate symptoms.”
Everyday writing:
- ✅ “This is a long-term commitment, not a quick fix.”
- ✅ “In the long term, small habits matter more than big gestures.”
Notice the pattern: whenever the phrase sits right before a noun (plan, investments, relationship), it’s hyphenated. Whenever it stands on its own after a preposition like “over,” “in,” “for,” or “on,” it’s two open words.
Short Term Follows the Exact Same Rule
If you’ve ever wondered about “short term” versus “short-term,” good news — it’s the identical logic, just the opposite end of the timeline.
- “We have a short-term goal.” (adjective, before a noun — hyphenated)
- “This will pay off in the short term.” (noun phrase — open)
Once you internalize the rule for “long term,” it transfers directly to “short-term,” “mid-term,” and similar time-based compounds, which is one reason grammar teachers treat this as a template rule rather than a one-off exception.
A Simple 3-Step Test You Can Run on Any Sentence
When you’re mid-sentence and unsure, run this quick check instead of guessing:
- Find the noun right after “long term.” Is there one immediately following it?
- If yes — hyphenate. “Long term” is modifying that noun as a compound adjective.
- If no — leave it open. “Long term” is standing alone as a noun phrase (or, per the exception above, following a linking verb).
This test works for roughly 95% of real-world sentences. The remaining 5% are house-style judgment calls, which is exactly why professional editors keep a style guide on hand instead of relying on memory alone.
Why This Actually Matters for Your Writing
It’s fair to ask whether one hyphen is worth this much attention. In casual texting, no. In professional or published writing, it adds up.
- Credibility: Inconsistent hyphenation is a small thing, but readers — and especially editors, recruiters, and clients — notice patterns of small errors and generalize from them.
- Clarity: In genuinely ambiguous sentences, the hyphen changes meaning. “Long term investors” (no hyphen) can misread as “long, term investors,” while “long-term investors” is unambiguous.
- Consistency at scale: If you’re producing a lot of content — a blog, a knowledge base, marketing copy — picking one convention and sticking to it (per a style guide) prevents the phrase from appearing three different ways across your own site, which looks like nobody proofread it.
Common Mistakes to Avoid
- ❌ “We need a long term plan.” — Missing hyphen before a noun. Should be “long-term plan.”
- ❌ “Investors focus on the long-term.” — Unnecessary hyphen; “long term” here is a noun phrase.
- ❌ “We want a longterm solution.” — Not standard; use “long-term solution.”
- ❌ Switching forms within the same document. Pick your convention (based on grammar, not preference) and apply it consistently across a piece.
Frequently Asked Questions
Is “longterm” ever correct?
Not in standard edited English. Major dictionaries and style guides don’t list it as a preferred spelling. You may see it in casual writing, social media, or as a stylized brand name, but that’s usage outside formal grammar rules, not an accepted alternate.
Do I hyphenate “long-term” after “is”?
Often not. Most style guides drop the hyphen after linking verbs like “is,” “are,” or “was” — for example, “the plan is long term” rather than “the plan is long-term.” Some house styles keep the hyphen anyway for consistency, so check your specific style guide if you have one.
Is “long term” one word or two?
It’s two words when it functions as a noun phrase (“plan for the long term”) and hyphenated when it functions as a compound adjective before a noun (“long-term plan”). It’s essentially never written as a single closed word in standard usage.
Which style guides address this rule?
AP Style and the Chicago Manual of Style both call for hyphenating “long-term” when it precedes and modifies a noun, and for leaving it open when it functions as a noun phrase. If you’re writing under a specific publication’s or company’s style guide, defer to that guide over general convention.
Does the same rule apply to “short-term” and “long-standing”?
“Short-term” follows the identical noun-vs-adjective rule as “long-term.” “Long-standing” is a slightly different case — some dictionaries now list “longstanding” as an accepted one-word variant, which “longterm” has not achieved.
Why do so many websites use “longterm” incorrectly?
Mostly because English has merged similar compounds before (email, website, online), so writers assume this one has followed the same path. It hasn’t — at least not according to current style guide consensus — so it’s worth treating those as separate cases rather than a general trend.
Conclusion
The long term vs. long-term question isn’t really about memorizing a spelling — it’s about noticing what job the phrase is doing in your sentence. Standing alone as a thing you’re referring to? Leave it open: long term. Sitting right before a noun, describing it? Hyphenate: long-term. And “longterm” as one word? Skip it — it’s not the standard, no matter how often you see it online.
Run the three-step test next time you hit this word mid-sentence, and it’ll stop being a pause-and-Google moment.
