To nestle means to settle into a cozy, protected, or comfortable position, like a bird tucking itself into its nest or a cat curling up in a warm blanket. When you nestle into your favorite reading spot with pillows all around you, you're arranging yourself in a way that feels snug and secure.

A small cabin might nestle among tall pine trees, tucked into the forest in a way that feels natural and sheltered. A baby nestles against its mother's shoulder. You might nestle a fragile ornament into tissue paper when packing it away, surrounding it with soft protection.

The word suggests gentle adjustment, a kind of settling in that creates warmth and security. When something nestles or is nestled, there's usually softness involved, along with a feeling of being surrounded or embraced. A village nestled in a valley sits protected by hills on all sides, and when you nestle into bed on a cold night, you're burrowing into comfort and safety as you settle in.
