A wainwright is someone who makes wagons and carts for people to use. They work with wood and other materials to build these kinds of vehicles that can be pulled by animals like horses. It's kind of like building a big toy car, but instead of playing with it, it's used for important jobs like carrying things from one place to another. Wainwrights were really important back in the old days before cars were invented, because wagons and carts were one of the main ways for people to get around and move things from one place to another. Even though we don't see them as much anymore, some people still use wagons and carts today, and there are still wainwrights who make them.
