Secondary predicate

A secondary predicate is like a mini-sentence that helps give more information about the subject of the main sentence. Imagine you're playing with toy cars and you have a red one. If you say "My car is red," "red" is the main predicate because it tells you something about your toy car. But if you want to say more about your car, you might say "My car is red and fast." Here, "fast" is the secondary predicate because it gives you more information about your car. It's like a little extra detail that helps you understand the main idea better.
