What Is the Correct Spelling: Long Term or Longterm?
Quick Answer
The short answer to long term or longterm is this: “long term” (two words) and “long-term” (hyphenated) are both correct, depending on how the phrase is used in a sentence. “Longterm” as a single word is not considered standard English by any major dictionary or style guide.
Why the Confusion Exists
The long term or longterm debate exists because English often merges common phrases into single words over time think “online” or “nowadays.” Writers assume the same pattern applies here, but “long term” has not made that shift. Search engines also show a mix of correct and incorrect spellings, which adds to the confusion.
Dictionary Consensus
Every major English dictionary agrees on the long term or longterm question: the one-word spelling is What Is the Correct Spelling Long Term or Longterm

Understanding the Difference Between Long Term and Long-Term
Long Term as a Noun Phrase
When “long term” refers to a stretch of time rather than describing something, it stays open as two words. Example: “This strategy will pay off in the long term.” Here, the phrase behaves like a noun and follows a preposition such as “in” or “for.”
Long-Term as a Compound Adjective
When the phrase sits directly before a noun and describes it, it becomes “long-term” with a hyphen. Example: “She has a long-term goal.” The hyphen tells the reader that “long-term” is working as one descriptive unit, not two separate words.
Easy Rule to Remember
If a noun comes right after the phrase, hyphenate it. If the phrase stands on its own, leave it open. This one rule solves almost every long term or longterm question you will ever run into.
