Snug means fitting closely and comfortably, like a favorite sweater that hugs your body without being too tight, or a pair of gloves that fit your hands perfectly. When something is snug, it feels secure and cozy, not loose or baggy.

You might wear a snug winter hat that keeps your ears warm without slipping down over your eyes. A cat curled up in a snug spot between the couch cushions has found a place that wraps around it perfectly. When you tuck yourself into bed and pull the covers close around you, you're getting snug and warm.

The word also describes small, comfortable spaces. A snug cabin might not have much room to spare, but everything fits together neatly and feels welcoming. Sailors talk about making things snug on a ship, meaning they've secured everything tightly so nothing will shift or fall when the boat rocks.

The feeling of being snug is pleasant: protected, warm, and just right. It's the opposite of drafty, loose, or uncomfortable. When your dad checks that your seatbelt is snug before a car trip, he's making sure it's tight enough to keep you safe but not so tight it's uncomfortable.
