Sense: adjective/1
All four words describe pleasant indoor spaces, but they emphasise different qualities. 'Spacious' is purely about size — a spacious room has plenty of floor area, but could still be dark or stuffy. 'Bright' focuses only on light: a bright room may actually be small or poorly ventilated. 'Well-ventilated' is more technical, often used in real-estate listings or building codes, and stresses air circulation alone. 'Airy' is the most holistic of the four: it suggests that a room feels open, light, and full of fresh air all at once. A studio apartment can be airy without being spacious if it has tall windows and a high ceiling; a warehouse can be spacious without being airy if it lacks light and circulation.

Etymology
Formed in Middle English from the noun 'air' plus the adjective ending '-y', meaning 'having the qualities of air'. The earliest senses (14th–15th century) referred literally to things made of or located in the air. The figurative senses developed gradually: the 'light in texture' meaning grew from the idea of containing air; the 'nonchalant manner' and 'unrealistic' meanings extended from the older sense of being as light and weightless as air itself, with no solid grounding.
