Share means to let others use or have part of something that belongs to you. When you share your crayons with a classmate, you're letting them use some while you keep using others. When you share a sandwich with a friend, you're each getting part of it.

Sharing shows up everywhere in daily life. Siblings share a bedroom, students share equipment in science class, and neighbors might share tools or lawnmowers. People share information too: a teacher shares knowledge with students, and friends share secrets or stories with each other.

A share can also be a noun meaning your portion of something. If five friends split a pizza equally, each person gets one share (one-fifth). In business, a share is a piece of ownership in a company. When someone owns shares of stock, they own a small part of that business.

The word also means to have something in common with others. You might share a birthday with your cousin, or share an interest in astronomy with a friend. Two cities might share a border.

Notice that sharing doesn't always mean giving something away permanently. When you share your bike with your brother for an afternoon, you still own it. Sharing means being willing to let others benefit from what you have, whether that's objects, space, time, or experiences.
