The word "greenhouse" is a straightforward compound of "green" (Old English grēne, meaning the color or vitality of plants) and "house" (Old English hūs, meaning a dwelling or structure). The term emerged in the 17th century to describe glass structures designed to trap heat and sunlight, fostering plant growth. The logic is literal: a "house" that maintains "green" (plant life) by creating a warm microclimate.
