Long-time vs. Longtime – Which is Correct?
Both long-time and longtime can be correct when they function as adjectives meaning “having existed, continued, or been associated for a long period.” In modern American English, longtime is generally the preferred closed spelling, while long-time remains an accepted hyphenated variant in many contexts when needed by a house style.
Long-time or Longtime – Which is Correct?
Long-time and longtime are both valid American English compound adjectives. They describe someone or something that has existed, continued, or been connected with another person or organization for a long period.
In most contemporary American writing, longtime is the more common and generally preferred spelling, especially before a noun: “a longtime customer.” The hyphenated form, long-time, is also used, particularly by publications or organizations whose style guides prefer hyphens in compound modifiers.
Do not confuse either adjective with the separate noun phrase a long time. For example, write “We waited for a long time,” not “We waited for a longtime.”
The Best Trick to Remember the Difference
Use longtime as the default adjective before a noun: “a longtime friend.” Use a long time when you are talking about duration as a noun: “She stayed for a long time.” You may also remember that the hyphenated long-time is an alternative compound-adjective spelling, while the two-word form long time expresses duration.
This distinction resembles Overtime vs. Over Time, where spacing changes grammatical meaning and usage.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| long-time | Adjective | Existing or associated for a long period | She is a long-time supporter of the project. |
| longtime | Adjective | Existing or associated for a long period | He is a longtime supporter of the project. |
How to Use Long-time
Long-time is a hyphenated compound adjective. It usually appears directly before a noun to show that a person, relationship, practice, or condition has continued for an extended period. It is grammatically correct in American English, although many modern style guides prefer the closed form longtime.
The hyphen helps show that long and time work together as a single modifier. The spelling is most common in phrases such as “a long-time employee,” “a long-time resident,” and “a long-time partner.”
Example 1: The long-time director announced her retirement.
Example 2: He is a long-time contributor to the magazine.
Example 3: The restaurant has remained a long-time favorite among local residents.
Etymology of the word Long-time
Long-time combines the adjective long, descended from Old English lang, with the noun time, descended from Old English tīma. English writers gradually began combining such words into compound modifiers. The hyphen indicates that the two words function together as one adjective.
How to Use Longtime
Longtime is the closed compound-adjective form of the expression. It means having existed, continued, or been associated for a long period. In current American English, it is often the best default choice in edited prose, especially when it appears before a noun.
Use longtime for descriptions such as “a longtime friend,” “a longtime customer,” “a longtime resident,” or “a longtime employee.” It is neutral in tone and works in both professional and casual writing.
Example 1: The longtime manager thanked the staff for their support.
Example 2: A longtime resident spoke at the community meeting.
Example 3: The company celebrated its longtime partnership with the charity.
Etymology of the word Longtime
Longtime developed from the same two English words as long-time: long and time. As frequently used compound modifiers became familiar, some began appearing as closed compounds without a hyphen. American dictionaries and usage guides recognize longtime as a standard adjective.
Related Concepts
Understanding compound modifiers and duration expressions makes the distinction between long-time, longtime, and a long time easier to apply.
- Compound adjectives: Two or more words can combine to act as one adjective before a noun. Depending on usage and style, the words may be hyphenated or written as a single word.
- Duration expressions: The phrase a long time functions as a noun phrase and refers to an extended period. It is not interchangeable with the adjective longtime.
- Hyphenation: Hyphens can clarify that multiple words modify one noun together. However, familiar compounds may eventually become closed forms, as happened with longtime.
Examples from Media and Literature
The following examples reflect the way these forms commonly appear in published writing, journalism, and entertainment-related language:
- News writing: A report may refer to a “longtime community leader” when introducing a person known for years of local involvement.
- Sports coverage: Articles often describe a coach as a “longtime team manager” or a “long-time coach,” depending on the publication’s style.
- Film and television coverage: Entertainment journalists may call an actor a “longtime collaborator” of a director.
- Biographical writing: A biography might describe someone as a “longtime friend” of a public figure.
- Fiction: A novel may introduce a character as a “longtime neighbor” to establish a relationship that predates the story.
