Loan words
Borrowed and reshaped - from Swedish, Russian, and now English. Finnish bends a loan word until it inflects like a native one.
Finnish does not borrow lightly. A word that comes in gets reshaped until it can take Finnish endings, which is why the origin is often invisible until somebody points it out.
The layers are historical: Swedish from centuries of shared administration, Russian through Helsinki's slang, and now English through work and the internet. Each card says where the word came in and how the shape changed on the way.
Common questions
Why do Finnish loan words look so different from the original?
Because Finnish phonology will not tolerate most foreign shapes - consonant clusters at the start of a word get simplified, and a final vowel is usually added so the word can inflect. The result is a word that behaves like a native one.
Are English loan words taking over Finnish?
They are arriving steadily in work and internet vocabulary, and Finland has an unusually active institution documenting it. In practice most get Finnicised on the way in rather than staying English.
