http://www.wordiq.com/definition/Finnish_languageThe Finnish linguistic situation is to some extent comparable to that of much of the Arabic speaking world, where Classical Arabic is used in official and religious speech and in the literature, whereas colloquial forms of Arabic are used in everyday conversation and in personal letters.
There are two main varieties of Finnish used throughout the country. One is the kirjakieli, or the book language, and the other puhekieli, or the common language. The kirjakieli, as its name implies, is used nearly in all of the written texts, not always excluding even the dialogue of common people in popular prose. It is also usually used in church sermons, political speech and newscasts. Puhekieli, on the other hand, is the main variety of Finnish to be used in popular TV and radio shows, at workplaces and it is sometimes preferred to speaking a dialect in personal communication. Also, the kirjakieli is quite rare in personal letters and in conversations in the Internet.
The puhekieli has mostly developed naturally from earlier forms of Finnish, and spread from main cultural and political centers. The kirjakieli, however, has always been a consciously constructed medium for literature. It preserves grammatical patterns that have mostly vanished from the colloquial varieties and, as its main application is writing, it features complex syntactic patterns that are not easy to handle when used in speech. The puhekieli develops significantly faster, and the grammatical simplifications includes also the most common pronouns and suffixes, which sums up to frequent but modest differences.
Finnish children usually aquire the knowledge of kirjakieli when educated in school, but many children who read much learn it as their (written) "first language".
