Ingrian grammar

Many words in Ingrian display consonant gradation, a grammatical process where the final consonant of a root may change in some inflected forms. Gradated words have two forms, called the strong grade and the weak grade. Follows a list of consonant gradations present in Ingrian, with examples:

Strong	Weak	Example (nom. sg.)	Example (gen. sg.)	Translation
k	∅	jalka	jalan	"foot, leg"
nk	ng	kenkä	kengän	"shoe"
t	∅	vahti	vahin	"guard"
lt	ll	ilta	illan	"evening"
rt	rr	merta	merran	"basket"
nt	nn	ranta	rannan	"shore"
st	ss	riista	riissan	"thing"
p	v	apu	avun	"help"
mp	mm	kumpa	kumman	"which"
pp	p	leppä	lepän	"alder"
uut, yyt oot, ööt	uuvv, yyvv oovv, öövv	suuto	suuvvon	"court"
Vut	Vvv	rauta	ravvan	"iron"
Vuk	Vvv	leuka	levvan	"jaw, chin"
Vit	Vij	maito	maijon	"milk"
Vik	Vj	poika	pojan	"boy, son"
eik, iik	eij, iij	reikä	reijän	"hole"

In nominals and verbs alike, consonant gemination is an active process where a consonant following a light, uneven syllable, if followed by an (underlyingly) open syllable with a long vowel or a diphthong, is geminated. This process can be seen in the following examples:

sana ("word") → kaks sannaa ("two words")

käkö ("cuckoo") → kaks käkköä ("two cuckoos")

This gemination should not be confused with consonant gradation: Both can occur in one word. For instance, pittää ("to keep") has both consonant gradation and gemination:

pittää ("to keep"); miä piän ("I keep"); höö pitävät ("they keep")

Consonant gemination does not affect consonants that start an uneven syllable:

literatura ("literature"); literaturaa ("into the literature")

Some (recent) loanwords aren't affected by gemination either:

inženera ("engineer"); kaks inženeraa ("two engineers")

In the Soikkola dialect, there is a phonological distinction between primary geminates (those that were originally present in Proto-Finnic) and secondary geminates (those formed as a result of gemination). Primary geminates are realised as long, while secondary geminates are short. In the other dialects of Ingrian, both types of geminates are equally long.[1]

In contrast with consonant gemination, nouns that do not have an even number of syllables and do not have a penultimate light syllable, experience vowel elongation in the inessive and adessive endings, where the final vowel becomes long:

paikka ("area") → paikaas ("in the area"), koira ("dog") → koiraal ("on the dog")

orava ("squirrel") → oravaal ("on the squirrel"), Soikkola ("Soikinsky Peninsula") → Soikkolaas ("on the Soikinsky Peninsula")

If the noun has consonant gradation, the weak grade determines the vowel length of the inflectional ending:

poika ("boy") → pojal ("on the boy")

In some subdialects of the Soikkola dialect, this rule also holds true in the elative and ablative cases:

orraava ("squirrel") → orraavaalt ("off the squirrel"); paikka ("area") → paigaast ("from the area")

Ingrian nouns have thirteen noun cases. Unlike some plural pronouns, nouns don't have the accusative case and its function is taken over by either the genitive in the singular or the nominative in the plural.

Case	Suffix	English prep.	Example	Translation
nominative (nominativa)	-∅	—	talo	a house
genitive (genitiva)	-n	of/'s	talon	a house's
partitive (partitiva)	-(t)a / -(t)ä	a bit of	talloa	a bit of a house
illative (illativa)	-V	into	talloo	into a house
inessive (inessiva)	-s	inside	talos	inside a house
elative (elativa)	-st	out of	talost	out of a house
allative (allativa)	-lle	onto	talolle	onto a house
adessive (adessiva)	-l	on top of	talol	on top of a house
ablative (ablativa)	-lt	out of	talolt	out of a house
translative (translativa)	-ks	into (being)	talos	into (being) a house
essive (essiiva)	-nna / -nnä	as	talonna	as a house
exessive (eksessiva)	-nt	out of (being)	talont	out of (being) a house
comitative (komitativa)	-nka / -nkä	with	talonka	with a house

In the modern (spoken) language, the exessive case has grown to be obsolete. Furthermore, the comitative is only present in the Ala-Laukaa dialect of the Ingrian language, although it was adopted into the written language as well.[2] Some of the endings differ in dialects. In the Soikkola dialect, for instance, the essive ending is -Vn rather than -nna, yielding talloon.

The nominative case is used primarily to mark the subject of a verb:

Kana kaakattaa ("The chicken cackles")

Kana muni munan ("The chicken laid an egg")

Furthermore, it can be used as a form of address:

Mama, miä tahon söövvä ("Mum, I want to eat")

As mentioned above, the accusative isn't morphologically distinct from the genitive in the singular and the nominative in the plural. The accusative case is used to mark a direct object of a telic verb:

Poika sööp lihan ("The boy will eat the meat")

Tyttö näki koirat ("The girl saw the dogs")

The accusative is identical to the nominative when a direct object of an impersonal verb or a verb in the imperative mood:

Söö liha! ("Eat the meat!")

Söövvää liha ("The meat is eaten")

The partitive is used in a number of functions. First of all, it is used to mark a direct object of an atelic verb:

Poika sööp lihhaa ("The boy is eating the meat")

Tyttö näki koiria ("The girl was seeing the dogs")

Secondly, the partitive case is used with numerals (other than yks, "one") and determiners to designate amounts of an object:

Miul on kaks silmää ("I have two eyes")

Miä näin paljo koiraa ("I saw a lot of dogs")

The partitive can be used to designate indefinite amounts:

Miul on rahhaa ("I have money")

The partitive is used in comparative constructions to mark the object of comparison:

Miä oon paremp häntä ("I am better than him")

Finally, the partitive is used as an indirect object of some postpositions:

Tämä ono podarka miun lapsia vart. ("This is a present for my children")

The genitive is used primarily to mark a possession by the inflected noun:

Miä näin pojan koiran. ("I saw the boy's dog.")

Lapsiin pere on suur. ("The children's family is big.")

Furthermore, it is used as an indirect object of many prepositions and postpositions:

Talon al ei oo mittä. ("Under the house there isn't anything.")

Möö elämmä talon sises. ("We live inside the house.")

The illative is primarily used to describe a direction into something:

Miä mänin talloo. ("I went into the house.")

Miä tokuin merree. ("I fell into the sea.")

It is also used to mark the designation of an object:

Tämä poika tööhö ei kelpaa. ("This boy isn't fit for work.")

Furthermore, the illative is used to indicate a cause:

Miun emä kooli lässyy. ("My mother died of a sickness.")

Finally, the illative is used to denote a timespan during which something didn't happen:

En miä joont kahtee päivää. ("I haven't had a drink in two days.")

The inessive is primarily used to describe a location inside something:

Miä oon talos. ("I am inside the house.")

Miä ujun meres. ("I am swimming in the sea.")

It is also used to describe a duration during which something has happened:

Ei stroitettu Rim yhes päivääs. ("Rome wasn't built in one day.")

The elative is primarily used to describe a movement out of something:

Miä tulin talost. ("I came out of the house.")

Miä hyppäisin merest. ("I jumped out of the sea.")

It is furthermore used to describe the subject of some kind of information:

Miä luen lehmilöist. ("I am reading about cows.")

Miä kirjutan meijen maast. ("I am writing about our country.")

The elative is used to denote a domain to which an object belongs:

Miä oon paremp kaikist lapsist. ("I am the best of all the children.")

Kaikest miun perreest, miä suvvaan vaa miun emmää. ("Out of all my family, I only love my mother")

Finally, the elative is used to denote a material from which something is made:

Miä teki pöksyt täst kankaast. ("I made trousers from this fabric.")

Laps teki samoljotan paperist. ("The child made an airplane from paper.")

The allative is primarily used to describe motion onto something:

Miä hyppäisin kannelle. ("I jumped onto the table.")

Kolja pani koiran stoolille. ("Kolja put the dog on the chair.")

It is furthermore used in a dative function to mark an indirect object:

Miä annoin hänelle omenan. ("I gave him an apple.")

Mitä hää siulle saoi? ("What did he say to you?")

The adessive is primarily used to describe a location on top of something:

Miä issun kanneel. ("I am sitting on the table.")

Koljan koira lessii stooliil. ("Kolja's dog is lying on the chair.")

It is also commonly used in a construction with the verb olla ("to be") to denote a possession:

Miul ono kirja. ("I have a book.")

Lapseel ovat pöksyt. ("The child has trousers.")

In the Soikkola dialect, the adessive is used instead of the comitative to denote an instrument of an action:

Miä kirjutan krandoššiil. ("I am writing with a pencil.")

Miä kuuntelen korviil. ("I am listening with [my] ears.")

Finally, the adessive is used to denote a location in time:

Ööl suset jahtiivat. ("At night, the wolves hunt.")

Kesäl ilma ono lämmää. ("In summer, the weather is warm.")

The primary function of the ablative is to describe a motion off of something:

Miä hyppäisin kanelt. ("I jumped off the table.")

Kolja nosti koiran stolilt. ("Kolja picked the dog up from the table.")

It is furthermore used to mark a source of an action:

Miä sain hänelt omenan. ("I got an apple from him.")

Mitä hää siult kuuli? ("What did he hear from you?")

The primary function of the translative is to describe one's change of state towards being something:

Miä tahon noissa siun ystäväks. ("I want to become your friend.")

I konna muuttui käppiäks tytöks. ("And the frog turned into a beautiful lass.")

It is also used to denote that an action was or will be done by a specific point in time:

Hää noisen sinnua unohtamaa voovven lopuks. ("He will forget you by the end of the year.")

Pittää meille ostaa podarkoja hänen nimipäiväks. ("We need to buy birthday presents for her birthday.")

Finally, the translate is used in many fixed impressions:

Miä läkkään ižoraks. ("I speak Ingrian")

Tämä poika näyttiijää oikiin käppiäks. ("This boy is (lit. seems) very pretty.")

The primary function of the essive is to describe one's current state of being:

Miun isä tekköö töötä kalastajanna. ("My father works as a fisherman.")

Miun emä ompelianna jaksaa laatia siun pöksylöjä. ("As a tailor, my mother can fix your trousers.")

It is also used to denote the point of time when an action occurs:

Pyhännä möö määmmä kirkkoo. ("On sunday we will go to church.")

Nimipäivännä miä sain paljo podarkoja. ("On my birthday I received a lot of presents.")

The exessive is a rare case, and is practically not used outside of the literary language. It's used only to describe a change of state out of being something:

Miä tuli pois ompeliant. ("I stopped being a tailor.")

A stem is the part of a word that can be changed by adding inflectional endings, and in most nominals corresponds to the nominative singular.

Ingrian has several paradigms that involve a vowel that all endings are added onto. When pluralised, however, this vowel might change:

stem vowel	English	nom. sg.	gen. sg.	part. sg.	ill. sg.	nom. pl.	gen. pl.	part. pl.	ill. pl.	Notes
-a	chicken	kana	kanan	kannaa	kannaa	kanat	kannoin	kannoja	kannoi	Followed by nominals ending in -a when following a syllable with a, e or i and recent loanwords.
-a	dog	koira	koiran	koiraa	koiraa	koirat	koiriin	koiria	koirii	Followed by native nominals ending in -a when following a syllable with o or u.
-ä	summer	kesä	kesän	kessää	kessää	kesät	kessiin	kessiä	kessii
-a/-ä	parent	vanhemp (<*vanhempa)	vanhemman	vanhempaa	vanhempaa	vanhemmat	vanhempiin	vanhempia	vanhempii	Followed by nominals with historically an underlying final -a or -ä that underwent full vowel reduction.
-e	leaf	lehti (<*lešte)	lehen	lehtiä	lehtee	lehet	lehtilöin	lehtilöjä	lehtilöihe	Followed by nominals where (pre-)Proto-Finnic *-e regularly changed to -i.
-i	guard	vahti	vahin	vahtia	vahtii	vahit	vahtiloin	vahtioloja	vahtiloihe	Followed by relatively recent borrowings, from after the Proto-Finnic period, ending in -i.
-o/-ö, -u/-y	birch	koivu	koivun	koivua	koivuu	koivut	koivuin, koivuloin	koivuja, koivuloja	koivuihe, koivuloihe
-VV	earth	maa	maan	maata	maaha	maat	maijen	maita	maihe	Followed by nouns ending in long vowels and diphthongs. The illative takes on the final vowel, unless it's i, in which case the ending is -e.

Other nouns have their endings attached on a consonant base.

The largest group of these are nouns ending (underlyingly) in a -i, which resemble e-stems like lehti. The only difference between this paradigm and that of e-stems is the partitive singular, where the ending is added onto the consonant and is -ta (-tä), rather than -a (-ä).

The final consonant of these nouns must be either h, l, m, n, r, s or t:

English	nom. sg.	gen. sg.	part. sg.	ill. sg.	nom. pl.	gen. pl.	part. pl.	ill. pl.
tongue	keeli	keelen	keeltä	keelee	keelet	keeliin	keeliä	keelii
big	suur (<*suuri)	suuren	suurta	suuree	suuret	suuriin	suuria	suurii

Due to historical reasons, some nouns in this class have an irregular change of the stem:

English	nom. sg.	gen. sg.	part. sg.	Notes
knife	veitsi	veitsen	veistä	In a cluster -Cs, the partitive singular stem is -s.
child	laps	lapsen	lasta
water	vesi	veen	vettä	Word-final *-ti regularly became -si.
five	viis	vijen	viittä
snow	lumi	lumen	lunta	m assimilates to the following t.
one	yks	yhen	yhtä	In the nominative singular and in the plural, *-kt became -ks, while in the singular and nominative plural it became -ht (~ -h)

Some nouns historically ended on a consonant. In these nouns, the consonant before the final vowel is gradated:

English	nom. sg.	gen. sg.	part. sg.
daughter	tytär (<*tüt'är)	tyttären	tytärtä

A final subclass of such nouns are those ending in -ut (-yt). These exhibit an irregular illative ending and form the plural differently from e-stem nouns:

English	nom. sg.	gen. sg.	part. sg.	ill. sg.	nom. pl.	gen. pl.	part. pl.	ill. pl.
Sun	päivyt	päivyen	päivyttä	päivyesse	päivyet	päivyein	päivyeitä	päivyeisse
beer	olut	olluen	olutta	olluesse	olluet	olluein	ollueita	ollueisse

Another large group of nouns in Ingrian end in the consonant -s. These, again, come in various inflection types:

stem consonant(s)	English	nom. sg.	gen. sg.	part. sg.	ill. sg.	nom. pl.	gen. pl.	part. pl.	ill. pl.	Notes
-nt-	third	kolmas	kolmannen	kolmatta	kolmantee	kolmannet	kolmansiin	kolmansia	kolmansii	Before -i, the stem consonants change to -ns-. In the partitive singular, the stem extends to -tt-.
-h-	man	mees	meehen	meestä	meehee	meehet	meehiin	meehiä	meehii
-∅-	column	patsas	patsaan	patsasta	patsaasse	patsaat	patsain	patsaita	patsaisse	In the Soikkola dialect, the stem consonant -h- is retained (for instance, the genitive singular is patsahan)
-ks-	treason	petos	petoksen	petosta	petoksee	petokset	petoksiin	petoksia	petoksii
-ks-	law	oikehus	oikehuen	oikehutta	oikehuee	oikehuet	oikehuksiin	oikehuksia	oikehuksii	The stem consonants only appears in the plural; In the singular, the stem-final -s is elided, while in the partitive, the stem extends to -tt-.

A third group includes nouns ending in the consonant -n:

stem consonant(s)	English	nom. sg.	gen. sg.	part. sg.	ill. sg.	nom. pl.	gen. pl.	part. pl.	ill. pl.	Notes
-s-	fly	kärpäin	kärpäisen	kärpäistä	kärpäisee	kärpäiset	kärpäisiin	kärpäisiä	kärpäisii	In some words, like ihmiin ("human"), the vowel preceding -n is shortened in inflected forms.

Finally, some nouns ending in -e have an underlying stem consonant -∅-:

stem consonant(s)	English	nom. sg.	gen. sg.	part. sg.	ill. sg.	nom. pl.	gen. pl.	part. pl.	ill. pl.	Notes
-∅-	boat	vene	venneen	venettä	venneesse	venneet	vennein	venneitä	veneissee	Compare this noun class to nouns like patsas ("column"). In this class, too, the Soikkola dialect retains the stem consonant -h- (for instance, the genitive singular is venneehen).

The comparative degree of Ingrian adjectives is generally formed by adding the suffix -mp to the adjective:

Positive degree	English	Comparative degree	English
korkia	"high"	korkiamp	"higher"
noori (noore-)	"young"	nooremp	"younger"

In some cases, a stem-final -a, -ä is transformed into an -e- in the comparative:

Positive degree	English	Comparative degree	English
vanha	"old"	vanhemp	"older"
pitkä (pitä-)	"long"	pitemp	"longer"

The comparative degree of the adjective inflects just like any other nominal:

Ingrian	English
suuremp poika	"the bigger boy"
suuremman pojan	"of the bigger boy"

Note that comparative endings have an underlying final vowel -a (or -ä in front-vocalic words).

Unlike Finnish and Estonian, Ingrian doesn't have a superlative degree morphologically distinct from the comparative. Instead, a form of the indefinite pronoun kaik ("all") is used together with the comparative:

Ingrian	English
kaikkia suuremp poika	"the biggest boy" (literally: "the boy bigger than all")
kaikkiin suuremp poika	"the biggest boy" (literally: "the boy biggest of all")
kaikkiis suuremp poika	"the biggest boy" (literally: "the boy biggest among all")

Furthermore, the adverb samoi (borrowed from the Russian самый) can be used together with either the positive or comparative form of the adjective to express a superlative:

Ingrian	English
samoi suur poika	"the biggest boy" (literally: "the most big boy")
samoi suuremp poika	"the biggest boy" (literally: "the most biggest boy")

Unlike in Finnish, personal pronouns can be used to refer to both animate and inanimate nouns alike. Follows a table of personal pronouns:

	1st person		2nd person		3rd person
	singular	plural	singular	plural	singular	plural
Nominative	miä ("I")	möö ("we")	siä ("you")	töö ("you")	hää ("he, she, it")	höö ("they")
Accusative	miun	meijet	siun	teijet	hänen	heijet
Genitive	miun	meijen	siun	teijen	hänen	heijen
Partitive	minnua	meitä	sinnua	teitä	häntä	heitä
Illative	miuhu	meihe	siuhu	teihe	hännee	heihe
Inessive	mius	meis	sius	seis	hänes	heis
Essive	miunna	meinnä	siunna	teinnä	hänennä	heinnä
Comitative	miunka	meijenkä	siunka	teijenkä	hänenkä	heijenkä

Other locative cases are formed using the appropriate nominal case endings to the inessive stem.

As seen above, Ingrian does not have grammatical gender, so the pronoun hää can be used for both male, female and inanimate referents alike. However, inanimate nouns are often referred to using the demonstrative pronoun se ("this") instead.

Some variation occurs among different dialects of Ingrian in regards to the personal pronouns. First of all, dialects with mid vowel raising exhibit the plural pronouns myy, tyy and hyy for möö, töö and höö respectively.[1][3] Furthermore, in the Ala-Laukaa dialect, the third person singular pronoun hän is found instead of hää. Similar forms have been found also in the now-extinct Hevaha and Ylä-Laukaa dialects.[3]

Since verbs in Ingrian conjugate according to grammatical person and number, subject personal pronouns may be omitted in Ingrian.

Ingrian demonstratives can be used both as pronouns and as determiners in a determiner phrase. There are three sets of demonstratives: proximal (near to the speaker), distal (far from the speaker) and neutral, which is used to refer to an object without specifying its relative location is space, and is often used in anaphoras:

	Proximal		Distal		Neutral
	singular	plural	singular	plural	singular	plural
Nominative	tämä ("this")	nämät ("these")	too ("that")	noo ("those")	se ("this, that")	neet ("these, those")
Accusative	tämän	nämät	toon	noo	sen	neet
Genitive	tämän	näijen	toon	noijen	senen	niijen
Partitive	tätä	näitä	toota	noota	sitä	niitä
Illative	tähä	näihe	tooho	noohe	siihe	niihe
Inessive	täs	näis	toos	noos	siin	niis
Elative	täst	näist	toost	noost	siint	niist
Allative	tälle	näille	toolle	noolle	sille	niille
Adessive	täl	näil	tool	nool	sil	niil
Ablative	tält	näilt	toolt	noolt	silt	niilt
Translative	täks	näiks	tooks	nooks	siks	niiks
Essive	tämännä	näinnä	toonna	noonna	senennä	niinnä

The proximal demonstatives can be contracted to tää (< tämä), tään (< tämän) and näät (< nämät). Again, in dialects with mid vowel raising, the distal demonstratives are tuu and nuu rather than too and noo respectively.[3] Furthermore, in the Ala-Laukaa and the extinct Hevaha dialects, as well as among some speakers of the Soikkola dialect, the plural neutral pronoun is ne rather than neet.[3]

The genitive and accusative singular of the neutral demonstrative pronoun are often used interchangeably, counter to the prescriptive usage described in Junus (1936). Furthermore, for most speakers of the modern Soikkola dialect, the functions of the distal demonstrative have been taken over by the neutral pronoun (se/neet).

Ingrian interrogatives are divided into one that has an animate referent (ken, "who?") and one that has an inanimate referent (mikä, "what?"). Originally, the latter is a combination of the pronoun *mi- and the interrogative clitic -kä, but its inflected forms are still formed on the basis of the free pronoun:

	Animate	Inanimate
Nominative	ken	mikä
Genitive	kenen	minen
Partitive	ketä	mitä
Illative	kehe	mihe
Inessive	kes	mis
Essive	kenennä	minennä

Other locative cases are formed using the appropriate nominal case endings to the inessive stem.

The interrogatives also have plural forms of the nominative, ket and mit respectively. Other case forms are used in the singular and plural alike. Like in Finnish and Estonian, but also English, the interrogatives are also used as relative pronouns:

Mikä ono? ("What is it?")

En tiije, mikä ono. ("I don't know, what it is.")

Ingrian verbs inflect for three persons, two numbers, and feature a separate impersonal form.

Number	Person	Suffix	Example	Translation
singular	first	-n	(miä) etsin	I search for
	second	-t	(siä) etsit	you (sg.) search for
	third	-V	(hää) etsii	he/she/it searches for
plural	first	-mma / -mmä	(möö) etsimmä	we search for
	second	-tta / -ttä	(töö) etsittä	you (pl.) search for
	third	-Vt -vat / -vät	(höö) etsiit etsivät	they search for
impersonal		-taa / -tää	etsitää	one searches

The impersonal form may always be used to denote the third person plural.

Ingrian verbs inflect for four moods: indicative, conditional, imperative and potential. Of these, the potential is very rare.

The indicative mood is the only one to feature an past tense separate from the present tense and not formed by means of modal verbs.

Mood	Suffix	Example	Translation
pres. indicative	-∅	(hää) tahtoo	he/she/it wants
impf. indicative	-i	(hää) tahtoi	he/she/it wanted
conditional	-is(i)	(hää) tahtois	he/she/it would have wanted
potential	-ne	(hää) tahtonoo	he/she/it may want

The imperative paradigm is highly irregular compared to the other three moods, and occurs only in the second and third person, as well as the impersonal:

Number	Person	Suffix	Example	Translation
singular	second	-∅	(siä) taho	want! (sg.)
	third	-koo / -köö	(hää) tahtokoo	he/she/it must want
plural	second	-kaa / -kää	(töö) tahtokaa	want! (pl.)
	third	-koot -kööt	(höö) tahtokoot	they must want
impersonal		-ttakoo / -ttäköö	tahottakkoo	one must want

Like nominals, verbs can be divided into a number of inflectional classes, according to which they are inflected, each class associated with a particular form of the stem.
