to wait up for
Have you ever stayed awake late at night because someone was coming home? Maybe a parent waiting for their teenager, or a roommate expecting a friend? In English, we say you’re waiting up for that person. This warm, everyday phrase is perfect for talking about care, concern, or simple plans after dark.
What Does “to wait up for” Mean?
“To wait up for” means to stay awake later than usual to greet, meet, or talk to someone who is coming home or arriving late. Think of it like keeping the lights on and the door unlocked until they’re safe inside. It’s not about “waiting” and “up” as separate words—it’s one idea: staying awake on purpose for someone.
When to Use It
You’ll hear “to wait up for” in personal, caring situations:
• At home with family (“My mom always waits up for me.”)
• Between roommates or partners (“Don’t wait up for me—I’ll be really late.”)
• In stories or movies about late-night arrivals
It’s informal to neutral—great for speaking, texts, or casual writing. You wouldn’t use it in formal reports, but it fits perfectly in daily life.
Example Sentences
- I told my sister not to wait up for me after the concert.

Mini Dialogue

Lena: “Okay, but don’t worry—I won’t wait up for you. Just be safe!”
Common Mistakes to Avoid
Don’t use “wait up for” when you’re just staying awake for yourself (like watching TV). It always involves another person. Also, don’t drop the “for”—you must say “wait up for [someone].”
❌ Don’t: “I waited up last night.” (Waited up for whom?)
✅ Do: “I waited up for my brother last night.”
Practice Tip
Think of someone you’ve waited for—or who’s waited for you. Say out loud: “I waited up for ______.” or “______ waited up for me.”
Final Note
Now you can use “to wait up for” to show care, set boundaries, or share a sweet moment in English! Keep using it in real life—it’s a small phrase with a lot of heart. You’re doing great!
