feed

The word "feed" has a wide range of meanings, but they all grow from one central idea: giving something what it needs in order to live, grow, work, or continue. Most often, it means giving food to a person or animal: "She carefully fed the baby," or "We need to feed the stray cat." It can also describe the act of eating, especially for animals: "The cattle are feeding in the meadow."

But feed goes far beyond meals. It can describe supplying almost anything that is needed, such as water, power, material, or information. A stream feeds a river, fuel feeds a fire, and a factory feeds raw material into a production line. In these examples, the word often suggests a steady flow from one place into another.

In the digital age, "feed" is also a common noun for a stream of updated content. Your "social media feed" is the running list of posts you see from other people, and a "news feed" brings in new stories as they appear. Here, the idea of steady supply is still there, but the thing being supplied is information.

As a verb, it can also mean to make a feeling or condition grow stronger: "His success fed his ambition." It may also describe the way one thing leads directly into another: "The cable feeds into the back of the television." Whether it is about food, fuel, movement, or information, feed usually points to the same basic picture: something is being supplied so that something else can continue, grow, or function.
