Finland Swedish
Finland Swedish is regulated by the Institute for the Languages of Finland. Official Swedish is not supposed to be very different from Swedish as found in Sweden. There are however e.g. words regarded as archaic in Sweden, but commonly used in Finland, and terms that differ from their counterparts in Sweden, often because of slight differences in the related legislation.
