Other forms: pressed; pressing; presses
To press something is to push it, like if you press an elevator button or press your friend to tell you a secret. If you get that secret, don’t leak it to the press, which is another word for news media.
Press is also a noun, meaning a machine that uses pressure, either to squeeze liquid out of something (like an apple cider press), or to stamp a design or text on something (like a printing press). There's also a press of people, or a crowd of folks so close they press against each other; and "the press," or the news media, which got the name because newspapers are printed using a press.
