Follow up and followup are related forms, but they are not always used in the same way. In modern English, follow up is usually a verb phrase, while follow-up (with a hyphen) is commonly used as a noun or adjective.
The closed form followup is uncommon and is accepted only by a few style guides or organizations.
This confusion exists because English often changes two-word phrases into compound words over time.
In this guide, you will learn the correct spelling, grammar rules, British and American usage, common mistakes, examples, and when to use each form with confidence.
Quick Answer
The correct choice depends on how you use the word.
- Follow up (two words) = Verb
- Follow-up (hyphenated) = Noun or adjective
- Followup (one word) = Rare and generally avoided unless a company style guide requires it.
Examples
✅ I will follow up with you tomorrow.
✅ Please schedule a follow-up meeting.
✅ The doctor arranged a follow-up appointment.
❌ I will followup with you tomorrow.
For most writing, use follow up as the verb and follow-up as the noun or adjective.
The Origin of Follow Up or Followup
The phrase follow up first appeared in English during the 18th and 19th centuries. It simply meant “to continue after an earlier action.”
Over time, writers began using follow-up as a compound noun to describe the next action, meeting, visit, or message.
Examples include:
- follow-up email
- follow-up appointment
- follow-up question
Some companies later started writing the word as followup in internal documents or software labels to save space. However, major dictionaries and style guides still recommend follow up or follow-up in most situations.
The spelling difference exists because English commonly changes phrases into compound words over many years, but followup has not become the standard spelling.
British English vs American English Spelling
Unlike words such as colour and color, British and American English generally follow the same rule for follow up.
Both varieties prefer:
- follow up as a verb
- follow-up as a noun or adjective
The one-word form followup is uncommon in both regions.
| Usage | British English | American English |
|---|---|---|
| Verb | follow up | follow up |
| Noun | follow-up | follow-up |
| Adjective | follow-up report | follow-up report |
| One word | Rare | Rare |
Examples
British English:
- We will follow up next week.
- A follow-up letter was sent.
American English:
- I’ll follow up tomorrow.
- The patient needs a follow-up visit.
