Hygge
Etymology
Borrowed into Danish from a Norwegian word meaning "well-being," likely tied to Old Norse "hyggja" ("to think, feel satisfied") and to the same root as English "hug." It entered wide English use around 2016 during a wave of Scandinavian lifestyle interest.
noun · /HOO-guh/
A Danish sense of cozy, warm contentment, usually shared with others in simple comfort.
What it names
A specific quality of atmosphere — candlelight, blankets, good company — that English can only gesture at with "coziness."
Example
They spent the storm indoors with tea and a slow fire — pure hygge.
Related idea
Gemütlichkeit, its German cousin, adds a note of belonging and geniality; hygge leans more toward quiet, sensory coziness.
