Short answer: Use “catch up” (two words) when it’s a verb – an action, like “Let’s catch up soon.” Use “catch-up” (hyphenated) when it’s a noun or adjective, like “We had a catch-up meeting.” “Catchup” (one word) is a recognized but less common spelling of ketchup – and only informally used as shorthand for the other two.
My first month at a marketing job, I sent my manager an email saying I’d “catch-up on the reports by Friday.” She replied with just one line: “Catch up, not catch-up ” – no explanation, just that tiny correction sitting in my inbox like a red flag. I remember staring at it, genuinely confused, because I’d never even considered that a hyphen could change whether something was an action or a thing.
I went down a rabbit hole that night trying to understand why.
Years later, I still think about that email every time I type the phrase – which is honestly the whole reason I’m writing this.
The Three Forms at a Glance
Catch Up (Verb)
“Catch up” is a phrasal verb. It describes an action – something you do, not something you have, It always stays as two separate words.
It can mean:
To reach the same level as someone after falling behind
To get updated on recent news or events
To finish something you’re behind on
To reconnect with someone after time apart
Examples:
I need to catch up on my emails.
Let’s catch up next week.
She’s trying to catch up with the rest of the class.
Catch-Up (Noun or Adjective)
When the idea turns into a thing rather than an action, it takes a hyphen. As a noun, “catch-up” names a meeting, call, or session. As an adjective, it describes something designed to help you catch up.
Examples:
We scheduled a quick catch-up before the meeting. (noun)
This is a catch-up session for new hires. (adjective)
I’m behind, so I need a catch-up call with my manager. (adjective)
Catchup (One Word)
This is where most explanations get it wrong. “Catchup” isn’t just a sloppy version of “catch up” or “catch-up.” According to Merriam-Webster, it’s a genuine – if less common – spelling of ketchup, the condiment.
Example:
She put catchup on her fries similar-looking words like scraped and scrapped.
Some informal writing also uses “catchup” as a shorthand for the verb or noun forms above, but this isn’t standard, and it risks confusion with the condiment. In formal or professional writing, avoid it for anything other than ketchup.
How to Know Which One You Need
Ask yourself one question: Is it an action, or is it a thing?
Describing something you’re doing? Catch up (two words)
Naming a meeting, call, or session – or describing one? Catch-up (hyphen)
Talking about the condiment? Catchup (one word, rare spelling)
Catch Up vs. Catch-Up vs. Catchup — At a Glance
| Form | Part of Speech | Example |

Common Mistakes to Avoid
Using “catch-up” as a verb.
I need to catch-up on work.
I need to catch up on work.
The hyphenated form only works as a noun or adjective – never as the action itself.
Dropping the hyphen in noun or adjective use.
We had a catch up meeting.
We had a catch-up meeting.
Without the hyphen, “catch up meeting” reads as two unconnected words rather than a single descriptive term.
Assuming “catchup” is just a typo.
It isn’t a misspelling of “catch up” – it’s a real, dictionary-recognized word, just one with a different primary meaning (ketchup). If you mean the verb or the meeting, use “catch up” or “catch-up” instead.
