To sue someone means that you want to go to a court and ask for money because someone has done something bad to you or has said something bad about you.
So, you sue someone for something.
- You can sue McDonald’s if you come across a spider in your Happy Meal.
- “I’ll sue that idiot, he has stolen my car!”

court = trials take place there and crimes are judged
to come across = find coincidentally, find/see something without looking for it
