Other forms: majuscules
A majuscule is just a capital letter — or a term for large script in which every letter is the same height. Now you know what your friend meant when she told you to write your lemonade stand sign in majuscule.
The term majuscule was originally used in the 18th century for an uppercase letter, from the Latin maiusculus, "somewhat larger," a close relative of major. Its antonym, minuscule, is much more commonly used today. You can feel free to impress your friends by using it for capital letters: "I wrote my whole essay using majuscule to make it look more impressive."
