The verb expand means to make something bigger or wider. It might refer to something concrete, as when you blow into a balloon and make it expand, or something more abstract, as when you study to expand your mind. Expand is a combination of the Latin words ex-, meaning out, and pandere, to spread.. The idea of spreading out was always there, though the current idea of something actually becoming larger was first recorded in the mid-17th century.
