Is it takeout or take-out?
It can be “takeout” or “take-out.” “Takeout” is a compound noun that means “food that you order from a restaurant to eat somewhere else” (e.g., “We didn’t have time to eat at the restaurant, so we ordered takeout”). In UK English, “takeaway” is more common.
“Take-out” (with a hyphen) is an adjective (as well as a compound word) that modifies a noun that pertains to the food that you can take out (e.g., “The line for take-out BBQ was too long, so we left”). The UK version of this is “take-away.”
Remembering when to use hyphens for the variations of phrasal verbs with take can be tricky. Luckily, QuillBot’s Grammar Checker can show you which version is right.
