run an errand

Use run an errand when you're leaving to do a short, necessary task. You can say, “I need to run an errand.” This signals you'll be away for a bit. Or, you can specify the errand, like “Can you run to the store for milk?” It’s super flexible. You can also use it in the past tense: “I ran an errand this morning.”

• Your roommate texts: “Hey, I’m running an errand to the dry cleaner’s. Back soon!”
• A parent tells their child: “Mommy needs to run an errand to the bank. Be good!”
• In a movie, a character might say: “I’ve got to run a quick errand before the big meeting.”
• You might tell your boss: “I’ll be back in 30 minutes; I just need to run an errand.”

Use run an errand for short trips with a clear purpose. Think: post office, pharmacy, grocery store, bank, or picking up a package. It’s for tasks that are part of your routine. It implies efficiency and a specific, often mundane, objective. It’s not for leisurely shopping trips or long journeys. It’s the opposite of lounging around.

Don't use run an errand for major tasks. Going on vacation? That’s not an errand. Starting a new business? Definitely not an errand. Visiting friends for fun? Nope, that’s socializing. It’s also not for tasks done at home. If you’re just tidying up your living room, you’re not running an errand. Unless, of course, you have to go out to buy cleaning supplies first! That would be the errand.

Learners often mix up errand with words like mission or task in ways that sound unnatural. While an errand *is* a task, the phrase run an errand has a specific feel. Using do a task is fine, but run a task sounds odd. Similarly, go on a mission implies something much bigger, like in video games or spy movies. Stick to run an errand for those quick, everyday trips.
