The term 'TALL-HAT WEARER' can be solved by the four-letter word 'CHEF'. A CHEF is a professional cook who is responsible for preparing meals in a restaurant or other food-serving establishment. They are typically trained in the culinary arts and have a wide range of skills related to food preparation. Chefs often wear tall hats, also known as toques, as part of their uniform. The hat is usually white and is used to signify the CHEF's rank and authority in the kitchen.
