The name "Moral" is of American origin and is a gender-neutral name meaning "Lovely Thoughts". A moral is a message or lesson conveyed through a story or event, often left for the audience to determine or encapsulated in a maxim. It is a lesson in a story or real life, with examples such as "slow and steady wins the race" from Aesop's fable of the Tortoise and the Hare. Morals have historically been present in literature, serving to instruct and entertain audiences, especially in classical drama and children's literature. In more recent children's literature, moral lessons are conveyed through fantasy and adventure stories, such as in J.K. Rowling's Harry Potter series. The ability to derive moral lessons from stories develops in children around the age of 9-10, as shown by developmental psychology research.
