Gezellig

If you google the word 'Gezellig' you will find:

'Gezellig is word that encompasses the heart of Dutch culture.

Gezellig is a word that you will hear a lot and locals and foreigners alike will tell you it cannot be translated.
Its meaning includes everything from cozy to friendly from comfortable to relaxing, and from enjoyable to gregarious...

According to Wikipedia, a perfect example of untranslatebility is seen in the Dutch language through the word gezellig, which does not have an English equivalent. Literally it means cozy, quaint, or nice, but can also connote time spent with loved ones, seeing a friend after an absence or general togetherness.

You'll hear the word a lot, so here are some indications as to how to understand and use it:
A Brown cafe is gezellig, a dentist's waiting room is definitely ongezellig.
Having drinks with friends ( especially if they are gezellige friends) in your cozy sittingroom listening to good music with your dog and cat on the rug in front of the fire is very gezellig. Having dinner with the in-laws from hell is most ongezellig...
Going out with friends for a meal in a restaurant with good ambiance is gezellig. Grabbing a bite at a MacDonald's is ongezellig, unless you're with friends who are gezellig, that can turn it round and make the experience gezellig.
Gezellig can be used as an affirmative when someone asks you to join them for something you're keen on.
'Fancy going for a drink after class?'   'Ja, gezellig!'
People can be gezellig (Oprah Winfrey) or ongezellig ( George W. Bush)
Houses can be gezellig, think lots of plants, nice lighting, warmly furnished,  fresh flowers and nicely arranged.
Cities can be gezellig (Amsterdam) or ongezellig (Rotterdam).'
The list goes on, you'll get the hang of it....'

Queen Beatrix is perceived as a warm and friendly person who puts others at their ease. Probably a more gezellige personality than Queen Elizabeth, who is perceived as more remote... Just illustrating a point here, don't sue me!
