fika = a coffee break (but so much more)
This post has been a long time coming. As the internet explanation below notes, fika is one of the first words you learn upon coming to Sweden. According to one person I spoke with, the word "fika" is apparently kaffe backwards, though I don't know how accurate this is.
Here's one explanation.
A social cup of coffee
Swedes prefer not to translate the word fika. They don’t want it to lose significance and become a mere coffee break. It is one of the first words you will learn when visiting Sweden, right after tack (thank you) and hej (hello).
Fika is much more than having a coffee. It is a social phenomenon, a legitimate reason to set aside a moment for quality time. Fika can happen at any time, morning as well as evening. It can be savoured at home, at work or in a café. It can be with colleagues, family, friends, or someone you are trying to get to know. It is a tradition observed frequently, preferably several times a day.
