Fika means ‘coffee’, ‘coffee break’ and as a verb ‘to drink coffee’, 'to take a coffee break’. The common opinion is that this word was created through so-called back-slang, by reversing the letters in kaffi – ‘coffee’ in Dalecarlian dialect. This is said to have happened in the so-called Skinnarmålet, a secret language used by leather workers in Dalecarlia and later by peddlers travelling around the country.
From fika comes fik, (ett fik, fiket, flera fik, fiken)‘café’, ‘coffee house’
(Fika efter means ‘to hanker after’; that is an unrelated word, see Nyfiken below)
