To feed means to give food to a person or animal. Parents feed their babies, farmers feed their livestock, and you might feed your dog dinner every evening. When you're hungry and someone makes you a sandwich, they're feeding you.

The word can also mean to supply or provide something continuously. A news website feeds you information throughout the day. A factory might have a machine that feeds paper into a printer. When you feed wood into a campfire, you're keeping it burning by giving it more fuel.

Feed can be a noun too: animal food, especially for farm animals like cows, chickens, or horses, is called feed. You might see bags of chicken feed at a farm supply store.

You'll also hear feed in some interesting expressions. When you feed someone a line, you're telling them something that might not be true, trying to make them believe it. A feedback loop happens when the result of something gets fed back into the process, creating a cycle. And social media platforms use the word feed for the stream of posts that appears on your screen, like a social media feed, constantly supplying you with new content to consume.
