But the autonomous expression alone does not explain what function is performed.
A self-employed clothing retailer, for example, is someone who sells clothing on their own, without having a physical or virtual store. The function requires the person to travel with several pieces for sale, showing the clothes at the customers' homes, or sometimes receiving them at their own home. A strict and careful control of expenses and stock is necessary, as the person works alone.
