snuggle
To cuddle closely in a warm, cozy, loving way.
To snuggle means to settle into a warm, cozy position close to someone or something you care about. When you snuggle under a soft blanket on a cold morning, you're wrapping yourself up and getting comfortable. When you snuggle with a pet, you're cuddling close together in a way that feels safe and content.
Snuggling involves both physical closeness and a feeling of comfort. A tired child might snuggle up to a parent while reading a bedtime story. You might snuggle into your favorite chair with a good book, or watch your cat snuggle into a patch of sunshine on the floor.
The word suggests something gentle and affectionate, not rough or distant. Snuggling happens when you feel relaxed and happy to be near someone or something. It's that moment when you pull a blanket a little tighter around your shoulders, sink a little deeper into the couch cushions, or lean against someone you trust, and everything feels just right.
