Etymology
Origin of alacrity
First recorded in 1500–10; from Latin alacritāt-, stem of alacritās “enthusiasm, zeal,” equivalent to alacer + -tās- noun suffix ( see -ty 2)
Explanation
Someone with alacrity shows cheerful willingness and eager behavior, like a kid whose mother has told him he can buy anything in a candy store. While the noun alacrity normally refers to someone's peppy behavior, it can also describe a certain mood or tempo of a musical composition, indicating how the music should be played. Alacrity comes from the Latin alacritas, and the Italian musical term allegro is a near relation.
