Although the word 'prince' dates back to at least 1225, the word 'princess' did not appear in English until about 1385. In the Middle Ages, women of noble or royal families were called 'Lady', with no other specific titles except 'Queen'.
In the 19th century, the term 'princess' was given to a size of roofing slate. Such slates also came in sizes called 'queen', 'duchess' and 'lady'.
The verb 'to princess' used to refer to a way of dressing meat, such as lamb, with inlaid slices of ham, carrot and parsley.
In the Aarne-Thompson classification system for folktales, there are 16 plots involving princesses. Andromeda in Greek mythology was the first princess to be saved from a monster by the hero.
