Beforehand means in advance or ahead of time, before something happens or before it's actually needed. When you prepare beforehand, you get ready before the moment arrives instead of scrambling at the last minute.

If your class is taking a field trip on Friday, studying the museum exhibits beforehand means looking at them earlier in the week so you know what to expect. A chef who chops all the vegetables beforehand has them ready when it's time to start cooking. When you pack your backpack the night before school, you're doing it beforehand rather than rushing around in the morning.

The word captures smart preparation and thinking ahead. Athletes often visualize their performance before the game starts, musicians practice before the concert, and students review their notes before the test. Doing something beforehand gives you confidence and reduces stress because you're not caught off guard.

You might hear someone say, “I should have known that beforehand,” when they wish they'd learned something earlier, or “Let me know beforehand if you need a ride,” when they want advance notice to plan accordingly.
