Finnish has two main dialect groups: Western and Eastern, with
numerous regional variations. Western dialects, influenced by
Scandinavian languages, tend to simplify word endings, while
Eastern dialects, influenced by Russian and Karelian, often have
softer consonants and longer vowel sounds. Some dialects, like
Savonian and Karelian, exhibit distinct phonetic and grammatical
features. Despite these variations, Standard Finnish, based on a mix
of Western and Eastern dialects, is universally understood and used
in formal settings.
