The term 'annexa' is technically incorrect. The correct word is 'adnexa,' which refers to parts attached to a main structure, especially in anatomy. Perhaps you are thinking of 'annex,' which means something attached, appended, or added. Think of it as an extension to a building, like adding a new wing to a school. It's not the original structure, but it's connected and serves a related purpose. Unlike independent structures, an annex is dependent on the main building.
