Cuddling or pressing close to someone in a warm, affectionate way for comfort.
From Scandinavian roots (compare Swedish 'snugga,' to cuddle), entering English in the 1600s. The '-le' ending creates a diminutive, intimate feel. The '-ing' form shows the action happening.
Humans aren't the only animals that snuggle—it's actually a deep mammalian behavior for thermoregulation and bonding; penguins huddle together to survive Antarctic cold, and it's basically the mammalian version of the same instinct!
