The new app was the brainchild of a team of young developers.
Brainchild → It is formed from "brain" (from Old English "brægen", meaning the organ of thought) and "child" (from Old English "cild", meaning offspring or product). The word "brainchild" refers to a product of one's intellect or creativity, akin to a child born from one's mind.
Think of your 'brain' as the source of ideas and 'child' as something you create — a brainchild is an idea or creation that comes from your mind.
