lend

To lend something means to let someone else use or borrow it from you for a little while.

When you lend something to someone, it's usually because you trust them and think they'll take good care of what belongs to you. This can be anything from money or a book to a tool or equipment that they need right away. Let's say your friend needs a bike to ride to work tomorrow and you have an extra one at home. If you lend it to him, he'll promise to return it in the same condition as when he borrowed it. You might even ask for it back by a certain date or time, but lending usually means that the item will be returned eventually.
