Gemütlichkeit is a German abstract noun whose closest English equivalent is cosiness. However, rather than basically just describing a place as not too large, well-heated and nicely furnished (a cosy room, a cosy flat), Gemütlichkeit connotes, much more than cosiness, the notion of belonging, social acceptance, cheerfulness, the absence of anything hectic and the spending of quality time in a place as described above.

The article went on to say that Queen Victoria was one of the first to use the adjective gemütlich in English; since it seems to be a useful word, I might be inclined to do the same. How would it be pronounced, though? Something like geh-MUTE-lish?
