Space Out – Meaning and Examples
Imagine sitting in a classroom or meeting, and your mind suddenly drifts away. You are looking at the speaker, but you aren’t hearing anything they say. When a person becomes inattentive, distracted, or starts daydreaming, we say they space out. This is a very common phrasal verb for describing a temporary mental absence.
What Does “Space Out” Mean?
The phrasal verb “space out” means to lose concentration or awareness of one’s surroundings; to become mentally detached or daydream. The term derives from the idea that one’s mind has drifted away into “space.” It usually refers to a temporary state of inattention, often caused by boredom, fatigue, or deep thought. The related noun is the descriptive phrase **spaced out** (adjective), meaning someone is distracted or unfocused.
When to Use It
You can use space out in casual settings when someone is clearly not paying attention.
- Meetings/Classes: During the long lecture, the students started to space out and look at their phones.
- Fatigue: I was so tired I completely spaced out and missed my exit on the highway.
- Boredom: The movie was so slow that I kept spacing out during the second half.
This phrase is informal and widely used.

Common Mistakes to Avoid
Do not use “space out” to describe an intentional mental break like meditation. It implies unintentional distraction.
❌ Don’t: “I need to space out for ten minutes to clear my mind before work.” (This is incorrect. Use “relax” or “take a break.”)
✅ Do: “He couldn’t focus; he just kept spacing out during the online lecture.” (This means he was unintentionally distracted.)
Practice Tip
Think of a situation where you were really bored. Write one sentence describing how you tried not to space out but failed.
Final Note
Using space out is a natural and casual way to describe a momentary lapse in attention. Practice this phrase to talk about distraction and focus!
