Large means big in size, amount, or extent. A large pizza feeds more people than a small one. A large dog like a Great Dane towers over a small dog like a Chihuahua. When someone orders a large drink at a restaurant, they're asking for more than the medium or small size.

The word works for physical things you can see and measure, but also for amounts and scales. A large crowd fills a stadium. A large vocabulary means you know many words. A store might carry a large selection of books, offering hundreds or thousands of choices.

Large is relative: what seems large depends on what you're comparing it to. An elephant is large compared to a mouse but small compared to a blue whale. A large classroom might hold thirty students, while a large concert hall holds thousands.

You'll often see large paired with other words to show scale: large-scale means something big in scope or ambition, like a large-scale construction project that builds an entire neighborhood. Someone might talk about an issue at large, meaning it affects everyone broadly, or a criminal at large, meaning they're free and not captured. When you by and large agree with something, you mostly agree with it overall, even if you disagree with some details.
