Catch Up vs. Catchup – Which is Correct?
The correct phrasal verb is catch up, written as two separate words. The single-word “catchup” is a common misspelling when referring to the act of reaching the same level or getting updated. While “catch-up” (hyphenated) functions as a noun or adjective, “catchup” (one word, unhyphenated) is incorrect for the verb phrase.
catch up or catchup – Which is Correct?
The distinction between “catch up” and “catchup” is straightforward: “catch up” (two words) is the universally accepted and correct form for the phrasal verb, meaning to reach someone or something that is ahead of you, or to get updated on information. The single-word “catchup” is a frequent misspelling that users often create due to phonetic confusion or a tendency to merge common phrases into one word. Although “catch-up” (hyphenated) is a valid noun or adjective (e.g., “a catch-up game”), the unhyphenated “catchup” is incorrect when used as a verb.
The Best Trick to Remember the Difference
To remember the difference, think of the action: you are trying to “catch” something “up” to your current position or knowledge. Both “catch” and “up” are distinct actions or directions. If you can insert another word between “catch” and “up” in some contexts (e.g., “catch her up on the news”), it reinforces their separation as individual words. Just like you wouldn’t write “runinto” for “run into,” keep “catch up” as two words for the verb phrase.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| catch up | Phrasal Verb | To reach the same point or level as someone or something else; to get updated. | I need to catch up on my emails after vacation. |
| catchup | Misspelling | An incorrect spelling when referring to the phrasal verb “catch up.” (Note: It is a less common variant spelling of “ketchup” the condiment, but not the intended meaning for the verb phrase.) | Incorrect: Let’s Correct: Let’s catch up later. |

Etymology of the word catch up
The phrasal verb “catch up” combines the verb “catch” and the adverbial particle “up.” The word “catch” originates from Old North French cachier, meaning “to chase, hunt, capture,” which itself comes from Latin captiare, a frequentative of capere “to take, seize.” The particle “up” comes from Old English upp, indicating an upward or higher position. The combination “catch up” to mean “to reach someone or something ahead” or “to get abreast of” became common usage in the English language by the 18th century.
Related Concepts
Understanding these related grammatical concepts can help clarify why “catch up” is written as two words.
- Phrasal Verbs: These are combinations of a verb and an adverb or a preposition (or both) that, when combined, create a new meaning distinct from the original verb. “Catch up” is a classic example, where “catch” and “up” together mean something more specific than just “catch” alone.
- Compound Words vs. Separate Words: English has many compound words (e.g., “sunflower,” “keyboard”) which are single words formed from two or more parts. However, many common phrases and phrasal verbs remain separate words, and incorrectly merging them into one word (like “catchup”) is a common error.

Frequently Asked Questions
Question 1: Is “catchup” ever a correct word in English?
“Catchup” (one word, unhyphenated) is not the correct spelling for the phrasal verb. It is a less common, archaic, or variant spelling of “ketchup” (the condiment), but this is not its primary or expected use. For the verb phrase, it is incorrect.
Question 2: What about “catch-up” with a hyphen? Is that correct?
Yes, “catch-up” (hyphenated) is correct when used as a noun or an adjective. For example, you might have a “catch-up session” (adjective modifying session) or play a “catch-up game” (noun describing the game). However, it is never used as the verb phrase.
Question 3: Why do people often misspell “catch up” as one word?
The misspelling often stems from phonetic spelling (it sounds like one word) and the common tendency for frequently used phrases to incorrectly merge into single words over time. Additionally, the existence of “catch-up” as a hyphenated noun/adjective can add to the confusion.
Conclusion
In summary, always use catch up as two distinct words when referring to the phrasal verb meaning to reach the same level, speed, or understanding. The single-word “catchup” is a common misspelling and should be avoided in formal and informal writing alike. Remember that “catch-up” (hyphenated) is a valid noun or adjective, but it serves a different grammatical function. A good pro tip for professional communication is to consistently use the correct two-word form of “catch up” to maintain clarity and credibility in your writing.
