What was a boy training to be a night called?

A boy training to be a knight was typically called a "page." Pages began their training around the age of seven, learning basic skills such as reading, writing, and horsemanship, before progressing to become a "squire" in their teenage years, where they received more advanced training in combat and chivalry. Ultimately, a squire could be knighted, completing the journey to becoming a full knight.
