Handbook of Finnish, 2nd edition, section 20 Spoken Finnish:

Dialects of Finnish

The scope of this presentation

This presentation describes some important features of Finnish dialects, in a coarse classification. The main purpose is to help people who read—as translators or otherwise—dialogs in Finnish literature. Such dialogs do not usually present genuine dialectal talk but rather a language with some dialectal features. Local dialects as such would often be too difficult to understand well even to native speakers of Finnish from other areas.

Regarding vocabulary, see notes about the dictionary of dialects.

The dialect areas

The following map describes the Finnish dialect areas. This presentation deals with the major areas only and even combining areas 1 and 2 into one.

The major dialect areas as described in this presentation are:

The areas are abstractions. In reality, the occurrence of dialect features varies greatly and often crosses the borders of the areas. For example, we can say that the first person singular pronoun is mie in Eastern dialects and mnää, mää, minä, or in Western dialects, but the areas where each of the form appears do not match exactly any of the areas in the map.

Eastern vs. Western dialects

Conventionally, the main division of Finnish dialects has been to Eastern dialects, itämurteet, and Western dialects, länsimurteet. Eastern dialects in the narrow sense consist of groups 7 and 8, i.e. Savonian and Southeastern dialects, but groups 5 and 6 have many features in common with them.

The consonant gradation of intervocalic t (as in katu : kadun in standard Finnish) has often been presented as typical of the division: Eastern dialects have a loss of consonant or semivowel j or v (e.g. kaun or kavun) whereas Western dialects have r or l (e.g. karun or kalun). Groups 5 and 6 are Eastern in this respect. Yet, they are mostly Western e.g. as regards to long vowels aa and ää in the first syllable: groups 7 and 8 usually have moa or mua instead of standard Finnish (and Western) maa.

Eastern and Western dialects have some vocabulary differences, too. The best-known difference is that most Eastern dialects use the noun vasta, Western dialects vihta for a sauna bath whisk made of birch twigs. Standard Finnish accepts both words and has no dialect-neutral alternative. Other Eastern – Western pairs are iltaehtoo (evening), nisuvehnä (wheat), paattivene (boat), suvikesä (summer), and virittää valkeasytyttää tuli (set up a fire). For these pairs, old written Finnish used Western words, but later Eastern words became standard. This explains why such Western words are now often understood as biblical or poetic and why they appear in derivations like ehtoollinen (Holy Communion, Lord’s Supper). On the other hand, for many word pairs, the Western word has remained standard and the Eastern word is recognized as dialectal or is in special use only.

Notes on the descriptions

The following subsections describe some typical features of each dialect area, with emphasis on differences from standard Finnish. Expressions of the form “A → B” are here to be read as “standard Finnish A corresponds to B in the dialects”, i.e. the arrow points from standard form to dialect form.

Some important phenomena have been omitted, since their occurrence varies greatly even within the areas. For example, words ending with -eA in standard Finnish have some different form in almost all dialects. Thus, korkea can be korkee (as in common spoken Finnish) or korkia or, in smaller areas, korkii, korkki, korkja, or korkie.

Yet another phenomenon not described is that Western dialects often have a short vowel in the first syllables in words that Eastern dialects and standard Finnish have a long vowel, e.g. hiihtäähihtää, pyyhkiäpyhkiä. This varies by word and by dialect. Besides, people may pronounce a half-long vowel in such words.

In the descriptions, general gemination refers to a phenomenon where a consonant is doubled between a stressed vowel and a long unstressed vowel or diphthong, e.g. kesääkessää, avaimet avvaimet. Here “stressed” refers to primary or secondary stress, so the phenomenon also occurs e.g. in yritetään yritettään (the third syllable, with e, has secondary stress).

1, 2 Southwestern dialects

3 Tavastian dialects

4 Dialects of Southern Ostrobothnia

5 Dialects of Central and Northern Ostrobothnia

6 Dialects of Northernmost Ostrobothnia

7 Savonian dialects

8 Southeastern dialects

These dialects have much in common with Savonian dialects but also some features of their own, and they lack some Savonian phenomena.
