First, I would like to explain what sommerhushygge is. It is a Danish word (it is a compounded word). A sommerhus is a house in the middle of nowhere (mostly) where you spend your free time in the summer and spring.
You might have heard about the famous word hygge. Hygge is a feeling, that I think have to be experienced.
Here is the best explanation I have heard of hygge:
Hygge is a calm comfortable time with people you love, a complete absence of frustrations or anything emotionally overwhelming. Often enjoyed with good food and drinks, warm blankets and candlelight.
Hygge is happiness.
The best explanation I have heard of sommerhushygge is this:
Sommerhushygge is enjoying the slow life in a Danish summer house.
I am going to spend the next 3 days with my grandparents in their sommerhus near Germany. I am looking forward to spending a lot of time with my family.
I am also going to study for my final exams (click here if you want to learn more about them).
