Long Term or Longterm is a spelling question with a clear answer. You should write it as two words, “long term,” when it is a noun phrase. Use the hyphenated form “long-term” only when it works as an adjective before a noun. This rule never changes, so you can stop guessing right now.
The mix-up happens because the letter “g” in “long” and the letter “t” in “term” run together in speech. Many writers forget the space or hyphen between them. In this article, you will learn the exact pattern for choosing the correct form every time. You will also see simple examples that make the rule stick.
American and British
Both American and British English follow the same rule. The noun phrase is two words: “long term.” The compound. Adjective takes a hyphen: “long-term.” There is no regional spelling difference. For example, “We plan for the long term” uses two words. “She has a long-term goal” uses a hyphen. The one-word form “longterm” is not standard in either dialect.
What Is the Correct Spelling: Long Term or Longterm?
This section breaks down the two correct spellings and explains why the one-word version is a mistake. You will learn the simple grammar rule that governs long term and long-term. Understanding this rule will help you write with more precision and confidence every time you use this common phrase.
Why the Confusion Exists
Writers often drop the hyphen or merge the words because they sound like one unit when spoken aloud. The stress pattern in speech makes “long term” feel like a single idea. This sound illusion leads people to write longterm as one word. Even though standard English grammar requires the space or the hyphen.
Quick Answer
Use long term (two words) when it is a noun. Use long-term (hyphenated) when it is an adjective before a noun. Never use longterm as one word. The hyphen transforms the phrase into a single descriptor, like in “long-term plan.”
| Correct Form | Incorrect Form | Example |
|---|---|---|
| long term | longterm | We are planning for the long term. |
| long-term | longterm | She has a long-term contract. |
Understanding the Difference Between Long Term and Long-Term
The difference between long term and long-term is a matter of grammar, not meaning. Both refer to an extended period of time. But, their roles in a sentence are completely different. One acts as a thing (noun), and the other acts as a description (adjective). Let us look at each role closely.
Long Term as a Noun Phrase
As a noun phrase, long term refers to the extended period of time itself. It is the object or subject of the sentence. You can often put an article like “the” or “a” in front of it. This signals that you are talking about the timeframe as a concept.
- In the long term, exercise improves your health.
- We are thinking about the long term, not just today.
- Investing for the long term requires patience.
Long-Term as a Compound Adjective
As a compound adjective, long-term describes a noun that comes directly after it. The hyphen joins the two words into one modifier. This tells the reader that “long” and “term” work together to describe the noun. For example, “long-term plan” clearly shows a plan covering many years. Never skip the hyphen in this position. It prevents confusion and keeps your writing clear.
- They signed a long-term lease.
- She needs long-term care.
- We are working on a long-term solution.
Why Longterm Is Usually Incorrect
The single word longterm appears in no major standard dictionary as a correct spelling. It is considered a spelling error in academic, professional, and formal writing. This section explains why it looks wrong to editors and how it compares to other compound words. For instance, “longtime” is accepted, but “longterm” is not. Editors expect the hyphen or the two-word form. Using “longterm” may hurt your credibility.
When Might You See Longterm?
You might see longterm in informal online comments, social media posts, or medical notes. Some medical and business dictionaries list it as a variant. But, for general and professional writing, stick to the standard two-word or hyphenated forms. Consistency with standard English is your safest choice.
Long Term vs Long-Term: Real Examples
Seeing the two correct forms side by side in real sentences helps solidify the rule. Pay attention to what follows the phrase. If a noun comes next, you need the hyphen. If the phrase stands alone or follows an article, it is a noun and stays as two words. See Merriam-Webster grammar and usage guide for more.
- ✗ We need a longterm strategy.
- ✓ We need a long-term strategy.
- ✗ Our focus is on the longterm.
- ✓ Our focus is on the long term.
A Simple Step-by-Step Method to Choose the Correct Form
Ask yourself two questions. First, is the word describing a noun right after it? If yes, use the hyphen: long-term. Second, is it the object of the sentence or after “the”? If yes, use two words: long term. If you answered no to both, you are probably using it wrong. See Cambridge Dictionary English grammar guide for more.
