Definition

To add on means to attach or include something extra in addition to what already exists.

To add on means to make something bigger by attaching an extra part or by including an extra item. It is often used for buildings and projects, as well as for services, fees, or features. The idea is that the original thing remains, and something additional is put on top of it.
