Is Allegro Italian or French?

Allegro is an Italian musical term that means "brisk, sprightly, cheerful." It comes from the Latin word alacrem, which means "lively, cheerful, brisk." The same Latin word also came into English as aleger, from Old French alegre. In music, allegro indicates a quicker tempo than andante, but not as quick as allegro. Allegro is also used as a noun to refer to a musical movement in such time. The term has been used in music since the 18th century, and it is derived from the Italian word allegro, which means "brisk, sprightly." The Latin word alacrem is also the source of the English word alacrity, which means "liveliness, briskness." Allegro is often used in musical compositions to indicate a lively and cheerful tempo.
