Consonant gradation
Consonant gradation is a type of consonant mutation found in some Uralic languages, more specifically in the Finnic, Samic and Samoyedic branches. It originally arose as an allophonic alternation between open and closed syllables, but has become grammaticalised due to changes in the syllable structure of the languages affected.
Definition
The term "consonant gradation" refers to a word-medial alternation of consonants between fortis and lenis realisations. The fortis strong grade appears in historically open syllables, while the lenis weak grade appears in historically closed syllables. The exact realisation of the fortis-lenis distinction differs between the branches. In the Samic languages it was realised through fortition, specifically lengthening, in the strong grade. In the Finnic and Samoyedic languages, there was instead lenition in the weak grade. Thus, the exact realization of the contrast is not crucial.Language | Alternation | Phonetic nature of alternation |
Estonian | sukk : suk-a : | Length overlong : long |
Finnish | sukka : suka-n : | Length long : short |
Estonian | ait : aid-a : | Tenseness tense voiceless : lax voiceless |
Finnish | aita : aida-n : | Voicing voiceless : voiced |
Finnish | lampi : lamme-n : | Manner of articulation stop : nasal |
Karelian | mušta : mušša-n : | Manner of articulation stop : fricative |
Finnish | kylki : kylje-n : | Manner of articulation stop : semivowel |
Finnish | teko : teon : | Presence of segment stop : zero |
Northern Sami | Sápmi : Sámi : | Presence of segment pre-stopped nasal : plain nasal |
Northern Sami | diehtaga : dieđa : | Presence of segment + articulation preaspirated stop : fricative |
Northern Sami | deadja : deaja : | Manner of articulation stop : semivowel |
Northern Sami | ruoktu : ruovttu : | Length + articulation long stop + singleton : short semivowel + geminate |
Northern Sami | baste : bastte : | Length long : short |
The language groups differ in regard to their treatment sequences of a vowel followed by j or w in Proto-Uralic. In the Samic languages, the second part of these remains phonologically a consonant, and can thus close the syllable before it, triggering the weak grade. It also takes part in gradation itself, lengthening in the strong grade. In Finnic, on the other hand, these were treated as diphthongs, and were equivalent to long vowels in terms of syllable structure. Consequently, they did not close the syllable and did not affect gradation.
Consonant gradation is understood to have originally been a predictable phonological process. In all languages that retain it, however, it has evolved further to a less predictable system of consonant mutation, of morphophonological or even purely morphological nature. This is a consequence of later changes in the structure of syllables, which made closed syllables open or vice versa, without adjusting the gradation. For example, in Northern Sami, the only difference between giella and giela is the grade; the consonant that originally closed the syllable in the genitive form has disappeared. Even in Finnish, which is relatively conservative with respect to consonants, there are many cases of strong grades in closed syllables and weak grades in open syllables, e.g. sade and sateen. These, again, are the result of changes in syllable structure, with the original Proto-Finnic *sadek and *sategen following the rules more obviously. In addition, not all Finnish words have gradation, so that the occurrence of gradation is not even morphologically predictable anymore, it is a property of each individual word.
Historical connections
There is no consensus view on the ultimate origin of consonant gradation in the Uralic languages. Three broad positions may be distinguished:- Gradation in Finnic, Samic and Samoyedic are all connected to one another.
- Gradation in Finnic and Samic are connected; gradation in Samoyedic is an unrelated phenomenon.
- There is no connection between gradation in any of the three language groups, and the similarities are accidental.
If a connection exists, it is also disputed what its nature may be, again allowing for three broad positions:
- Gradation is common inheritance.
- Gradation is an areal phenomenon that has developed through language contact.
- Gradation has developed independently in Finnic, Samic, and Samoyedic, based on a set of common s inherited from Proto-Uralic.
Finnic languages
The original effect of gradation in the Finnic languages can be reconstructed as a lenition of the consonant at the beginning of a closed syllable. Lenition caused geminate stops and affricates to shorten, and it caused already-short voiceless obstruents to become voiced:- *pp → *p̆p
- *tt → *t̆t
- *cc → *c̆c
- *kk → *k̆k
- *p → *b
- *t → *d
- *k → *g
The weakened grades of geminate consonants did not merge with the strong grades of the singleton consonants in Proto-Finnic, and still counted as geminates for the purposes of syllabification. There remained for a period an intermediate quantity, half-long *-t̆t-, which still closed the preceding syllable. Consequently, a syllable ending with a geminate in the weak grade still triggered a weak grade on the preceding syllable as well. In Finnish, the half-long consonants eventually merged with the strong-grade singleton consonants, but in most other Finnic languages, the strong-grade singletons underwent a secondary lenition which prevented this merger.
Gradation later expanded to include a pattern *s ~ *h, presumed to reflect a former pattern *s ~ *z. This type of gradation only systematically appears in cases of word-final *s, which between vowels uniformly becomes *h: Finnish pensas 'bush' has the genitive pensaan < *pensahen. An example is also found after a stressed syllable, however, in the exceptional monosyllabic root *mees : *meehe- "man"; and in a fossilized form, in the postpositions lähellä "near" vs. läsnä "present", reflecting the adessive and the essive of a root *läse- "vicinity". In cases of root-internal *s, this pattern is not normally found, though Votic later reintroduced a gradation pattern : here.
Veps and Livonian have largely leveled the original gradation system, and reflect both weak and strong grades of single stops as ; this may be an archaism or a substitution of voiced stops for fricatives due to foreign influence. Except for northernmost Veps dialects, both grades of geminate stops are also reflected as.
Finnish
Finnish consonant gradation generally preserves the Proto-Finnic pattern fairly well. The conditioning of syllable structure is still visible in most cases, but it is no longer productive: gradation has become a grammatical feature.Historical sound changes affecting realization of weak grades
- The weak grades *p̆p, *t̆t, *k̆k of geminates coincided with plain *p, *t, *k.
- The weak grades *mb, *nd, *ŋg of nasal+stop clusters were assimilated to geminate nasals, /nn, .
- The weak grades *lð, *rð of liquid+ clusters were similarly assimilated to geminate liquids,.
- *β merged with *ʋ. This may have been lost later. For example, the 3rd person singular suffix *-pi is represented by a chroneme, i.e. a lengthening of the preceding vowel; e.g. *tule-βi 's/he comes' → Old Finnish tuleu → Modern Finnish tulee.
- Between two unstressed short vowels, *ð and *h were lost ; these may be preserved in a variety of dialects.
- After a stressed vowel, *ð remained up until the dissolution of the Finnish dialects. It was lost entirely in Eastern Finnish, while Western Finnish dialects have varying reflexes: or in multiple western dialects, in the old Tavastian dialects, in archaic Southwestern and Northwestern dialects. As the area of shrunk throughout the 17th—19th centuries, standard Finnish developed as a spelling pronunciation of orthographical d, modeled after other languages such as Swedish, German and Russian.
- *ɣ also remained until the dissolution of the Finnish dialects. It was generally lost, but in the western dialects it may have become or .
- The geminate affricate *cc : *c̆c was fronted to a dental fricative *θθ : *θ. This sound has been lost in most dialects. Widely in Eastern dialects, both grades became, leading to loss of gradation. Standard Finnish was left with an unalternating , a spelling pronunciation similar to the case of. Other patterns found include unalternating ; alternating : ; alternating : ; alternating : ; and alternating ~.
Environment | Change | Strong | Weak |
-uku- -yky- | k→v | puku kyky | puvun kyvyn |
-lki- -rki- | k→j | kylki järki | kyljen järjen |
-nk- | /k/→ | sänky | sängyn |
j has been lost in this position in southeastern tavastian, northern bothnian and eastern dialects, resulting in kurki :kuren instead of the standard form Kurjen
Short t also has developed more complex gradation due to various assimilations. Patterns include t : d, rt : rr, lt : ll, and nt ~ nn.
Alternation patterns for p include p : v and mp : mm.
Analogical extension of gradation
The consonant clusters and were, comprising two obstruents, not originally subject to gradation. However, gradation pairs ht : *hð and hk : *hɣ were at one point introduced. The first of these patterns remains common in modern Finnish, e.g. vahti : vahdit 'guard'. The second is only found in a limited number of words, e.g. pohje : pohkeet 'calf : calves', but rahka : rahkat 'quark'. Usage varies for some words with, e.g. for the plural of nahka 'leather, hide', both nahat and nahkat are acceptable.Quantitative consonant gradation has expanded to include in addition to the pairs kk : k, pp : p, tt : t, also gg : g and bb : b in a number of recent loanwords, such as blogata : bloggaan 'to blog'; lobata : lobbaan 'to lobby'.
Historical sound changes affecting conditions of gradation
One important change was the loss of word-final *-k and *-h early on in the history of Finnish. This resulted in many open syllables with weak grades. In particular, the majority of nouns ending in -e are affected by this, with a weak grade in the nominative form. The imperative form of verbs also ended in a now-lost -k. For examples, side 'bandage', from *siðe, earlier *siðek ; hakea 'to get' → hae! 'get! ' from *haɣe, earlier *haɣek. Traces of the original syllable closure can be seen in sandhi effects: these classes of words can still be analyzed to contain the assimilative word-final 'consonant' ˣ, realized as lengthening of the next word's initial consonant. Therefore, hae side varastosta 'get a bandage from storage!' is pronounced, where the weak grades indeed occur in closed syllables.The loss of -k combined with loss of d were responsible for the modern Finnish infinitive ending, which was historically *-tak/täk. The final *-k triggered gradation, so that the ending normally became *-dak/däk. In turn, following the loss of d between unstressed vowels, and the loss of final *-k only *-aˣ/äˣ remained. Thus, hakea has only -a as the d was lost. But juo-da 'to drink' kept its d because of the stressed syllable preceding it. In the case of tulla 'to come', the earlier form was *tul-ðak, but the *ð was assimilated to the l according to the rules above. The original strong grade was preserved in hais-ta 'to stink' because of the preceding obstruent s which prevented gradation. However, in multiple Finnish dialects the word-final k has not completely disappeared, and instead it is preserved as the jumping of a consonant in next word, if it is located in the beginning of this word, yielding.
The situation appears differently in the many verbs ending in -ata/ätä. These verbs seem to have preserved the strong grade in the infinitive ending, going counter to the rules of gradation. However, historically it is in fact a weak grade: the stem of the verb itself ended in *-at/ät-, and this is still visible in the 3rd person imperative ending -atkoon/ätköön. Thus, when combined with the infinitive ending, the verb ended in *-attak/ättäk. The -k then weakened the consonant from a geminate *-tt- to a single *-t-, and later loss of -k resulted in the final form -ata/ätä. However, even though this is now a single consonant, it was originally a geminate and therefore triggers the weak grade on the syllable before it. So whereas the infinitive may be for example hypätä 'to jump', its original stem was *hyppät-, as can be seen in the first-person singular form hyppään 'I jump', from earlier *hyppäðen with loss of *-ð-.
An opposite effect was caused by the loss of *h and *ð between unstressed vowels. Loss of h affected nouns and adjectives ending in *-s or *-h, such as kuningas 'king'. In the nominative, this -s appeared as usual, and as the preceding syllable was closed, the weak grade ng appeared. But when a case ending such as the genitive -n was added, the result was originally *kuninkasen, which was then weakened to *kuninkahen, and the loss of -h- then resulted in the modern form kuninkaan. The intermediate steps are seen in mies 'man'. Here, following a stressed syllable, the -h- was not lost, so that its genitive is miehen.
Similar changes affected the illative ending, which was -hVn where V was the same as the vowel preceding the ending. The h is preserved after stressed syllables, as in maahan 'into the land', but lost otherwise as in kotiin 'into the home'. This explains why kotiin retains a strong grade even though a closed syllable follows it. The Pohjanmaa dialect of Finnish retains the -h-, however.
Words that now end in -e are in fact very similar to those ending in -s. These originally ended with -k or -h so that the nominative ended in a consonant just as kuningas and therefore the preceding syllable was in the weak grade. But after an ending was added, the weak grade g appeared, which eventually disappeared just as h did.
Analogical limitation of gradation
While syllabic gradation remains generally productive, the distortions of its original phonetic conditions have left it essentially a morphologically conditioned process. This is particularly visible in forms that display a strong grade where a weak would be historically expected, or vice versa. Possessive suffixes, in particular, are always preceded by the strong grade, even if the suffix may cause the syllable to be closed. For example, 'our bed' is sänkymme, not ˣsängymme.Strong grades may also be found in closed syllables in contractions such as jotta en → jotten.
Several recent loans and coinages with simple are also left entirely outside of gradation, e.g. auto 'car', eka 'first', muki 'mug', peti 'bed', söpö 'cute'. A number of proper names such as Alepa, Arto, Malta, Marko belong in this class as well.
Suffixal gradation has been largely lost, usually in favor of the weak grade. While the partitive plurals of kana 'hen' and lakana 'bedsheet' still show distinct treatment of the original *-ta, the partitive singulars in modern Finnish both have the weak grade, although in several dialects of older Finnish the form lakanata occurred for the latter. Similarly the participle ending *-pa is now uniformly -va, even after stressed syllables; e.g. syö-vä 'eating', voi-va 'being able'.
Karelian
consonant gradation is quite similar to Finnish: *β *ð *ɣ have been lost in a fashion essentially identical to Eastern Finnish, with the exception that assimilation rather than loss has occurred also for *lɣ and *rɣ. E.g. the plural of jalka 'foot' is jallat, contrasting with jalat in Finnish and jalad in Estonian.Karelian still includes some gradation pairs which Finnish does not. The consonants undergo consonant gradation when following a coronal obstruent : muistua 'to remember' → muissan 'I remember', matka → matan 'trip'. This development may be by analogy of the corresponding liquid clusters. On the other hand, some Karelian dialects do not allow for gradation in clusters beginning on nasals. Thus, the Olonets Karelian equivalent of Finnish vanhemmat is vahnembat.
The Karelian phoneme inventory also includes the affricate , which may be found geminated and is such subject to quantitative gradation: meččä 'forest' → mečäššä 'in forest'.
Votic
has two quantities for consonants and vowels, which basically match up with the Finnish counterparts. The Votic phoneme inventory includes a set of fully voiced stops, which Paul Ariste describes as being the same as in Russian. Thus, in addition to quantitative alternations between and, Votic also has a system of qualitative alternations in which the distinguishing feature is voicing, and so the voiceless stops are known to alternate with.As in Estonian, Karelian, and Eastern dialects of Finnish, the weak grade *ð of in inherited vocabulary has been lost or assimilated to adjacent sounds in Votic; the weak grade *β of has similarly become, or assimilated to in the cluster. However, the weak grade of survives, as before a back vowel or before a front vowel.
A noticeable feature of Votic is that gradation has been extended to several consonant clusters that were not originally affected. As in Finnish, this includes the clusters and with a voicing-neutral first member, but also further clusters, even several ones introduced only in Russian loans.
Gradation | Example | Translation | Notes |
s → z | isä → izässä | 'father' → 'father ' | - |
rs → rz | karsia → karzid | 'to trim' → 'you trim' | - |
hs → hz | lahsi → lahzõd | 'child' → 'children' | - |
tš → dž | retši → redžed | 'sleigh' → 'sleighs' | - |
ntš → ndž | tšentšä → tšendžäd | 'shoe' → 'shoes' | - |
ltš → ldž | jältši → jäldžed | 'footprint' → 'footprints' | - |
k → g | luku → lugud | 'number' → 'numbers' | From Proto-Finnic *k → *ɣ. |
hk → hg | tuhka → tuhgassa | 'ash' → 'ash ' | - |
ŋk → ŋg | aŋko → aŋgod | 'pitchfork' → 'pitchforks' | Retained intact from Proto-Finnic *ŋk → *ŋg. |
pk → bg | šāpka → šābgad | 'hat' → 'hats' | A recent Russian loanword. |
tk → dg | mutka → mudgad | 'hook, curve' → 'hooks, curves' | - |
sk → zg | pǟsko → pǟzgod | 'swallow' → 'swallows' | - |
šk → žg | šiška → šižgad | 'rag' → 'rags' | A recent Russian loanword. |
tšk → džg | botška → bodžgad | 'barrel' → 'barrels' | A recent Russian loanword. |
lk → lg | jalka → jalgad | 'foot' → 'feet' | From Proto-Finnic *lk → *lɣ. |
rk → rg | purkā → purgad | 'to take apart → you take apart | From Proto-Finnic *rk → *rɣ. |
The alternations involving the voiced affricate dž are only found in the Eastern dialects. In the Western dialects, there are several possible weak grade counterparts of tš:
Gradation | Example | Translation | Notes |
tš → ∅ | retši → rēd | 'sleigh' → 'sleighs' | - |
ntš → nď | tšentšä → tšenďäd | 'shoe' → 'shoes' | - |
ltš → ll | jältši → jälled | 'footprint' → 'footprints' | - |
rtš → rj | särtši → särjed | 'roach' → 'roaches' | - |
htš → hj | mähtšä → mähjäd | 'rye porridge' → 'rye porridges' | - |
stš → zz | iskeä → izzed | 'to strike' → 'you strike' | - |
Further minor variation in these gradation patterns was found down to the level of individual villages.
Votic also has a number of alternations between continuants which are short in the 'weak' grade, and geminates in the 'strong' grade, as well as more voicing alternations between palatalized stops, and the alternations between nasal+consonant~nasal+chroneme found in Finnish. Votic also includes alternations in which the 'strong' grade is represented by a short consonant, while the 'weak' grade is represented by a geminate: ritõlõn vs. riďďõlla. For comparison, the Finnish equivalents of these is riitelen 'I quarrel' vs. riidellä'' 'to quarrel'.
Estonian
Though otherwise closely related to Votic, consonant gradation in Estonian is quite different from the other Finnic languages. One extremely important difference is the existence of three grades of consonants ', weak grade paja 'pot ', overlong grade patta 'pot. This can be said to generally correlate with the existence of three degrees of consonant length, but since the alternation d ~ t occurs only after heavy syllables, and the alternations d ~ tt and t ~ tt occur only after light syllables, there is no single paradigm that has this simple alternation. However, weak grades like v, j, or ∅ that alternate with stops like b, d, or g originate from the weak grade of these stops, and these may still synchronically alternate with the over-long grades within the same paradigm, giving paradigms with three underlying grades.Another extremely important feature of Estonian gradation is that, due to the greater loss of word-final segments, the Estonian gradation is an almost entirely opaque process, where the consonant grade must be listed for each class of wordform. So, for example, embus 'embrace' has the same form for all cases, while hammas 'tooth' has weak grade mm in the nominative hammas and partitive hammast, but strong form mb in the genitive hamba and all other cases of the singular. There is a large number of cases in which inflectional endings are identical except for how they affect the consonant grade, e.g. leht 'leaf' belongs to a declension class in which both the genitive and the partitive singular are formed by adding -e, but the genitive takes the weak form, while the partitive takes the strong form. In the end, the types of generalizations that can be made are that some inflectional categories always take the strong form, some always take the weak form, some forms may take the overlong form, while other inflectional categories are underdetermined for whether they occur with weak or strong grade. In this last case, within a paradigm some forms are constrained to have the same grade and others are constrained to have the opposite grade; thus all present tense forms for the same verb have the same grade, though some verbs have strong and others have weak, and the -da infinitive has the opposite grade from the present.
The system of gradation has also expanded to include gradation of all consonant clusters and geminate consonants, when occurring after short vowels, and vowel gradation between long and overlong vowels, although these are not written except for the distinction between voiceless stops and geminate voiceless stops. E.g. linn, 'city ' vs. linna 'city '. In consonant clusters, in the strong grade the first consonant is lengthened, e.g. must, 'black ' vs. musta 'black '. Before single consonants, long vowels and diphthongs also become overlong in strong forms and remain merely long in weak forms, e.g. kool, 'school ' vs. kooli 'school '.
Samic languages
Gradation was present in Proto-Samic, and is inherited in most Samic languages. It is different from the gradation found in the Finnic languages in some important aspects:- Gradation applies to all consonants, even consonant clusters.
- Geminate stops and affricates were realised with preaspiration in Proto-Samic, and were thus phonetically distinct from singletons in more than length alone.
- Rather than featuring lenition in the weak grade, the weak grade generally reflects the original consonant. Instead, it is the strong grade that was modified: single consonants were lengthened into half-long in the strong grade, geminate consonants were lengthened to overlong.
- It only applies in consonants at the end of a stressed syllable; consonants following unstressed syllables remain unlengthened and do not show grade alternations.
In the Western Samic languages, geminate nasals became pre-stopped, which affected the strong grade of singletons as well due to the historical merger of these grades. In the languages in closest contact to Finnic, a number of developments towards the situation in Finnish and Karelian have occurred, such as the change of unlengthened *t to.
Northern Sami
has a system of three phonological lengths for consonants, and thus has extensive sets of alternations. Quantity 3 is represented as lengthening of the coda part of a geminate or cluster, which is absent in quantity 2. Quantity 1 consists of only an onset consonant, with the preceding syllable having no coda. In addition, most dialects of Northern Sami feature coda maximisation, which geminates the last member of a cluster in various environments.Most sonorants and fricatives are only subject to quantitative gradation, but nasals, stops, affricates and the glide are subject to both quantitative and qualitative changes. Some words alternate between three grades, though not all words do. Note that the following apostrophe marking the over-long grade is not used in the official orthography, although it is generally found in dictionaries.
Some gradation triads include the following:
Continuants | Quantity 3 | Quantity 2 | Quantity 1 |
đˈđ oađˈđi 'sleeper' | đđ oađđit 'to sleep' | đ oađán 'I sleep' | |
hrˈr skuhrˈri 'snorer' | hrr skuhrrat 'to snore' | hr skuhrai 'S/he snored' | |
mˈm cumˈmá 'kiss' | mm cummát 'kisses' | m namat 'names' | |
sˈs guosˈsi 'guest' | ss guossit 'guests' | s viesut 'houses' | |

dd | tt | ||
hkk | hk | g | |
gg | kk | ||
hčč | hč | ž | |
žž | čč | ||

zz | cc |
Samoyedic languages
Nganasan
, alone of the Samoyedic languages, shows systematic qualitative gradation of stops and fricatives. Gradation occurs in intervocalic position as well as in consonant clusters consisisting of a nasal and a stop. Examples of Nganasan consonant gradation can be seen in the following table :Gradation | Example | Gloss |
'wild reindeer' | ||
'berry' | ||
'back' | ||
'iron' | ||
'wave' | ||
'bow' | ||
'sod hut' | ||
'all' |
The original conditions of the Nganasan gradation can be shown to be identical to gradation in Finnic and Samic; that is, radical/syllabic gradation according to syllable closure, and suffixal/rhythmic gradation according to a syllable being of odd or even number, with rhythmic gradation particularly well-preserved.
Selkup
A limited form of consonant gradation is found in the Ket dialect of Selkup. In certain environments, geminate stops can alternate with short ones, under the usual conditions for radical gradation. E.g.:Gradation | Example | Gloss |
skin, hide | ||
hand |
