Swallowing is the action of moving food from your mouth into your body. It's what happens after you've chewed and it's time to take another bite.
When we talk about swallowing, we usually mean eating. If someone says "I'm having trouble swallowing," they might be talking about a medical problem that makes it hard for them to eat or drink. But in general, swallowing just means taking food into your body through your mouth and throat. It's something we do multiple times every day without thinking about it.
