Appendix:Finnish dialects

Finnish is a language with much regional variation, and there exists a traditional classification of Finnish dialects. Since the 1950s, increasing urbanization and mass media has caused an erosion of the dialects described by this classification. While Finnish still has regional variation, many features have spread and the traditional classification is no longer an accurate reflection of current Finnish dialects. Nevertheless, the traditional classification is widely used in Finnish sources and in discussions of historical Finnish (including in ), and the traditional larger groups are still mostly correct, so it is documented here.

The two major dialect groups in Finnish are the western dialects and the eastern dialects, in line with the usual west-east divide pervasive throughout Finland. The two branches are usually considered to belong to slightly different branches within the Finnic languages, with the eastern dialects being more closely related to the Karelian language than the western dialects, and not merely due to geographical proximity. The fact that Finnish is considered a single language today as opposed to two is due to extensive contacts between the western and eastern parts of Finland and cultural affiliation.

The classification includes some dialects not spoken in Finland, such as the varieties of Finnish spoken in parts of Karelia ceded to the Soviet Union after World War II, the Ingrian Finnish dialects, dialects spoken in northeastern Sweden and northern Norway, and the Värmland Savonian dialect of the. Also, some parts of Finland are not included, notably parts of the western and southern coast, including the southwestern archipelago, where no traditional Finnish dialects have survived after these areas became Swedish-speaking (see ). Modern varieties of Finnish spoken there are largely those of the surrounding areas, except for the Helsinki capital region in which the local Finnish variety cannot be classified as any of the traditional dialects.

A map of the traditional Finnish dialects can be found here, and a list can be found here. Both the map and the list are organized by ("parish"; more specifically a village with a church, historically an important administrative unit), by region and by the dialect branch (Western or Eastern dialects). Värmland is a major exception, as it is taken as the representative of all of the Forest Finn settlements in the area, mostly in Sweden but also partly in Norway. The list also groups dialects by the conventional dialect groups, of which there are eight (or seven, if southwestern transitional dialects are counted as southwestern dialects).

The major traditional dialectal groups are:
 * Western
 * Southwestern
 * Southwestern transitional dialects, as an intermediate group between Southwestern Finnish and Tavastian Finnish
 * Tavastian
 * South Ostrobothnian
 * North and Central Ostrobothnian
 * Lapland (Peräpohjola)
 * Eastern
 * Savonian
 * Southeastern

What follows is a description of each of the above groups and common features within each. Unless otherwise specified, Standard Finnish is taken as the reference variety.

Dialect groups

 * See here for a map of dialect groups.

The split between western and eastern Finnish dialects is well established in literature. The table below illustrates the common differences, but one should be reminded that they are not absolute, unconditional distinctions:


 * Some common definitions
 * represents any vowel unless otherwise specified.
 * represents any consonant.
 * is either or,  is either  or ,  is either  or , all depending on vowel harmony
 * represents final gemination.
 * Common gemination (, sometimes primary gemination) is when a consonant gets geminated when preceded by a stressed short vowel and followed by an unstressed long vowel or diphthong. It usually occurs after the simplification of vowel hiatuses, e.g. of &rarr;.

Southwestern dialects
The southwestern dialects are spoken primarily in Southwest Finland or Finland Proper.

Certain features are shared with Estonian, and some linguists have considered them to be evidence of Estonian influence on southwestern dialects.

The variety spoken in Rauma is particularly distinctive (among its characteristics is a pitch accent system) and is sometimes (humorously) called its own "language".

Common features:
 * Phonology
 * standard is either  or  (now all but extinct)
 * standard is either  :,  : ,  :  or  :  (the last two now all but extinct)
 * strong difference in rhythm between stressed and unstressed syllables
 * opening diphthongs are opened further: &rarr; /,  &rarr;,  &rarr;
 * if the first syllable is short, the short vowel in the second syllable may become semi-long (but not quite long) if it is preceded by a single consonant
 * (even in older borrowings)
 * (regionally) word-initial plosives may become semivoiced if preceded by n, m, l and (sometimes) t, rarely other voiced sounds
 * Phonotactics
 * word-initial consonant clusters are common (even in older borrowings)
 * Morphology
 * adjective ending usually, and then possibly affected by other phenomena, including southwestern gemination and vowel reductions
 * inessive ending
 * (regionally) as the past tense marker for verbs
 * the conditional mood marker for verbs may be to compensate
 * Southwestern gemination
 * the consonants, , , become geminated when preceded by a voiced sound and followed by a long vowel or diphthong (prior to reduction)
 * Vowel reductions (after gemination)
 * conditional reduction of diphthongs, e.g. &rarr;,  &rarr; ,  &rarr;
 * reduction of final vowels in bisyllabic words with an initial heavy syllable and all words with more syllables: short vowels are lost entirely (widespread apocope), long vowels become short
 * reduction/syncope of vowels in unstressed syllables if the next syllable starts with l, m, n, r, v, and if the first syllable is open (and usually only if it is long)
 * long vowels in non-initial syllables become short, some diphthongs may also reduce (particularly medial unstressed )
 * Other features
 * geminated l, m, n, r lose their gemination after a long or unstressed syllable
 * in many varieties, a diphthong (prior to reduction) often triggers the weak grade of the preceding consonant
 * (regional) a short vowel right before certain case endings tends to become long; often the case affected is a locational case, e.g. inessive, elative, adessive, ablative.
 * Pronouns: (standard ),  (standard )
 * Vowel reductions (after gemination)
 * conditional reduction of diphthongs, e.g. &rarr;,  &rarr; ,  &rarr;
 * reduction of final vowels in bisyllabic words with an initial heavy syllable and all words with more syllables: short vowels are lost entirely (widespread apocope), long vowels become short
 * reduction/syncope of vowels in unstressed syllables if the next syllable starts with l, m, n, r, v, and if the first syllable is open (and usually only if it is long)
 * long vowels in non-initial syllables become short, some diphthongs may also reduce (particularly medial unstressed )
 * Other features
 * geminated l, m, n, r lose their gemination after a long or unstressed syllable
 * in many varieties, a diphthong (prior to reduction) often triggers the weak grade of the preceding consonant

Southwestern transitional dialects
The transitional dialects display a mix of southwestern features and Tavastian features. They often lack e.g. reductions of later long vowels and diphthongs. Transitional dialects are spoken in large parts of Satakunta and parts of Tavastia and Uusimaa.

Tavastian dialects
The Tavastian dialects are spoken in the majority of Tavastia, including Pirkanmaa, as well as parts of Uusimaa and most of Kymenlaakso. They include the dialects that are perhaps the closest of all to modern Standard Finnish, although by no means still definitely identical. The group has a lot of internal variation and many common features are thus regional as well.

Common features:
 * Phonology
 * standard is either  or  (depending on the region)
 * standard is usually  :
 * opening diphthongs are opened further: &rarr; /,  &rarr;,  &rarr;
 * vowel sequences in later syllables often simplified: / &rarr;, / &rarr; /
 * unstressed diphthongs often lose the
 * Morphology
 * adjective ending usually, but in some parts also ,
 * the weak grade of  is often   (which may cause the following vowel to become long) or
 * the weak grade of is often, i.e. no special weak grade
 * Reduced word forms
 * the illative of the third infinitive is often replaced with an illative of the bare stem,
 * certain common verbs have shorter forms, e.g. &rarr; /,  &rarr; /,  &rarr; /,  &rarr; /
 * final and  at the end of a polysyllabic word is often assimilated into a following consonant or less commonly turned into final gemination unless before a major break
 * Other features
 * (regional) "common gemination"
 * (regional) Retaining in e.g. illative forms
 * (regional) a short vowel right before certain case endings tends to become (semi-)long; often the case affected is a locational case, e.g. inessive, elative, adessive, ablative.

South Ostrobothnian dialects
These dialects are spoken in a relatively well-defined area in South Ostrobothnia, and are perhaps the most internally consistent dialect group (to the point a lot of literature calls it the "South Ostrobothnian dialect" in the singular). It is believed to have some substrate influence from the southeastern (Karelian) dialects.

Common features:
 * Phonology
 * standard is
 * standard is  :
 * opening diphthongs are (overtly) further opened: &rarr; /,  &rarr;,  &rarr;
 * some vowel sequence changes: / &rarr; /, / &rarr; /
 * word-final may become  when followed by a voiced consonant
 * unstressed diphthongs often reduce to, including original  reduced in standard Finnish
 * Morphology
 * inessive ending or
 * in nominals belonging to the declension class, the nominative and partitive singular forms may exhibit an 'extra consonant':  (i.e. nominative singular, partitive singular ; mostly for earlier ),  (i.e. nominative singular , partitive singular ; mostly for earlier )
 * first-person/second-person plural verb endings, (standard , )
 * third-person verb forms with often labialized to /
 * Other features
 * "Savonian schwa" (see the Savonian dialects below), for clusters starting with, as well as the cluster
 * Retaining in e.g. illative and passive forms

Note: no "common gemination"

Central and North Ostrobothnian dialects
The Central and North Ostrobothnian dialects are spoken, as the name suggests, in North Ostrobothnia and Central Ostrobothnia. They contain Savonian influence, intensifying the closer one gets to the Savonian dialect area.

Common features:
 * Phonology
 * standard is 'generally lost', as in the Savonian dialects
 * standard is highly regional:
 * southern parts of Central Ostrobothnia: :
 * much of rest of Central Ostrobothnia: :
 * parts close to Savonia: :
 * most of North Ostrobothnia: :  or  :
 * some vowel sequence changes: / &rarr; /
 * may assimilate to a following plosive
 * (regional) opening diphthongs are opened further: &rarr; /,  &rarr;,  &rarr;
 * (regional) diphthongs often shift (even if stressed), e.g. &rarr;,  &rarr; ,  &rarr; , like in Savonian
 * Morphology
 * inessive ending or
 * adjective ending usually
 * the weak grade of  is often,  ( is an epenthetic vowel like in the "Savonian schwa")
 * first-person/second-person plural verb endings, (standard , )
 * (regional) first-person/second-person plural possessive ending
 * Other features
 * "common gemination"
 * "Savonian schwa" (see the Savonian dialects below), for clusters starting with, as well as the cluster

Lapland dialects
The Lapland or Peräpohjola dialects are spoken in much of Lapland (including / after which the dialect group is named in Finnish). They contain a mix of western and eastern features to the point they could reasonably be considered ti form their own northern branch, but nevertheless they are still traditionally counted in the western branch.

The varieties of the Lapland dialects spoken in Sweden and Norway have been recognized as their own official minority languages called Meänkieli and Kven, respectively. Their status as independent languages, which stems more from political than linguistic factors, is disputed.

Common features:
 * Phonology
 * standard is 'generally lost', as in the Savonian dialects
 * standard is usually  :
 * Morphology
 * archaic third-person plural ending instead of standard
 * Other features
 * Retaining in e.g. illative and passive forms, but it often undergoes metathesis and moves backwards in the word to after or even before the preceding consonant (a sequence like  often turns to  or even )
 * ,, , often ungeminate later in the word
 * (regional) "common gemination"
 * Pronouns: (standard ),  (standard ), regionally  (only in the nominative, standard ),  (only in the nominative, standard )

 * Pronouns: (standard ),  (standard ), regionally  (only in the nominative, standard ),  (only in the nominative, standard )

Savonian dialects
The area of the Savonian dialects is large, and it includes Savonia, Central Finland, Kainuu, the (north)eastern part of North Ostrobothnia (Koillismaa), North Karelia and even eastern parts of South Ostrobothnia. They are perhaps the most culturally recognizable dialect group.

The northernmost Savonian dialects in Kainuu and Koillismaa have been influenced by the North Ostrobothnian dialects and also the Karelian language in the east. The dialect once spoken by the Forest Finns in Sweden and Norway (the Värmland dialect) is also considered to belong in the Savonian group, but it lacks several features listed here, including the "Savonian schwa" and common gemination; some consider this evidence of the recency of these features in the Savonian dialects.

Common features:
 * Phonology
 * standard is generally lost: it may remain as  in,  after  and  after  or
 * standard is usually  :,  : ,  :  or  :
 * the long vowels and  diphthongize to / and / respectively when stressed, and may shift to  and  respectively when unstressed
 * the diphthongs often shift (even if stressed), e.g. &rarr;,  &rarr;  (or even ),  &rarr;  (or even )
 * unstressed diphthongs often reduce to just  or /
 * the consonants, , , , , may be palatalized if followed by a  or  (word-final  may thereafter be lost), or if preceded by a diphthong ending in , which may then be reduced to a simple vowel
 * Morphology
 * the plural marker used with words with stems ending in a rounded vowel or
 * the initial consonant of the clitic often assimilates to a preceding consonant or is lost entirely
 * the weak grade of  is often
 * the past active participle ending in the perfect/pluperfect and past connegative is often  (or, e.g. ); sometimes a 'double' ending  is seen
 * third-person verb forms with labialized to /
 * the third-person singular ending is retained in verb stems with an odd number of syllables
 * "Savonian schwa" (more properly an epenthetic vowel;, )
 * an additional vowel, often identical in quality to the preceding vowel or sometimes between the preceding and the following vowel, inserted between consonant clusters (not including geminated consonants)
 * the epenthetic vowel is always short and may be extra-short
 * the preceding syllable must be short, and the first consonant in the cluster must be or (regionally)  (in the Ostrobothnian dialects more broad)
 * Other features

Southeastern dialects
The southeastern dialects are spoken in South Karelia within Finland. Prior to the Second World War they were spoken in a much larger area, including Ladoga Karelia, the Karelian Isthmus, and Ingria (Ingrian Finnish dialects, not to be confused with the Ingrian or Izhorian language). They are sometimes just called the "Karelian dialects" (not to be confused with the Karelian language), even though the variety spoken in the Finnish region of North Karelia belongs to the Savonian dialect group. The Finnish population in the ceded regions was resettled in different parts of the country, diffusing the majority of the speakers.

Common features:
 * Phonology
 * standard is generally lost: it may remain as  in,  after  and  after
 * standard is regional:
 * on the isthmus and in Ingria: :

 * third-person verb forms with labialized to ///
 * the weak grade of  is often
 * the third-person singular ending is retained in verb stems with an odd number of syllables (mainly monosyllabic though), although the final  may then be lost, resulting in just
