What it means
Cozy is that soft, tucked-in kind of comfy where everything feels warm, calm, and zero-pressure. You use it for a room, a café, a night in, a game, even a whole vibe when it makes you want to curl up and stay there a bit longer.
Usage examples
"Rainy day, big blanket, a cozy game, perfect."

"This little bookshop’s so cozy I nearly forgot it was raining outside."
"Nah, I’m staying in tonight, hoodie on, lamp low, proper cozy vibes."
Where it comes from
Cozy is an older English word, also spelled cosy in British English. It’s been used for centuries to mean snug, warm, and comfortable. Online, especially in the 2010s and 2020s, it took on extra life as a whole aesthetic for gentle spaces, low-stress routines, and soft, comforting media.
