greenhouse
n.— «With cars, words and metal share territory: each brand’s vocabulary of shapes is collectively known as its design language. The beltline divides the greenhouse, or glassed-in upper body, from the portion that extends down from the window sills.…The angle of the windshield is known as its rake—an extreme tilt is said to be fast—while the inward angle of the side greenhouse windows is called the tumblehome.» —“Body Language: How to Talk the Designers’ Talk” by Phil Patton New York Times Apr. 1, 2007.
