The plural marker was -i-, added between a stem and a following case ending.
It has been preserved this way after short e̮ , u, ü, o e.g. paŋke̮-i-ллa ('by buckets') < paŋge̮-ллa ('by a bucket'), vävü-i-lē ('to sons in law') < vävü-lē ('to a son in law'), lintu-i-ллa ('by the birds') < linnu-ллa ('by a bird'), e̮htago-i-ллa ('in the evenings') < e̮htago-ллa ('in the evening').
It is less obvious now after numerous sound changes. See the "Pronunciation" chapter below.
A plural stem is always in the strong grade, if there is such a grade available e.g. lintu-i-ллa ('by the birds') < linnu-ллa ('by a bird').
Yet a plural stem of some dialects may be in the weak grade in front of a short vowel, if it is in the weak grade in singular e.g. pezä-llä ('on a nest') > pezi-llä ('on nests'), jaлga-ллa ('by a foot') > jaлgo-ллa ('by feet').
Long vowels and -i- melt together into diphthongs e.g. mā-ллa ('in a country') > mai-ллa ('in countries'), rattā-ллa ('by a wheel') > rattai-ллa ('by wheels').
Diphtongs e̮a and iä lost their last component in front of the plural -i- e.g. ke̮rke̮a-лē̮ ('into a high (place)') > ke̮rke̮i-лē̮ ('into high (places)'), pimeä-llä ('on a dark (way)') > pimei-llä ('on dark (ways)').
Short vowels have disappeared in front of the plural -i- or melt together with it into a long ī e.g. sepä-lē ('to a blacksmith') > seppī-lē ('to blacksmiths'), ärjä-lē ~ ärdžä-lē ('to an ox') > ärtšī-lē ('to oxen'), tšäe-llä ('on a hand') > tšäzi-llä ~ tšäsī-llä ('on hands'), naize̮-лē̮ ('to a woman') > naisī-лē̮ ('to women'), vanapa-лē̮ ('to an elder') > vanapī-лē̮ ('to elders'), sāttaja-лē̮ ('to an attendant') > sāttajī-лē̮ ('to attendants'), vokki-za ('in a spinning wheel') > vokkī-za ('in spinning wheels'). Yet:
a + -i- > e̮iin the second or third syllable, if the first syllable has o, u or e̮ ( The majority of e̮ stems belong here.) : e.g.
nurka-ллa ('on a corner') > nurke̮i-ллa ('on corners')
poiga-лē̮ ('to her son') > poike̮i-лē̮ ('to her sons')
se̮bra-лē̮ ('to a friend') > se̮bre̮i-лē̮ ('to friends')
sāttaja-лē̮ ('to an attendant') > sāttaje̮i-лē̮ ('to attendants')
a + -i- > oiin the third or second syllable, if the first syllable has i, a or e̮ ( Then it's counterpart in Kukkuzi dialect is probably a) : e.g.
adra-ллa ('by a plough') > adroi-ллa ('by ploughs')
kataga-ллa ('on a juniper') > katagoi-ллa ('on junipers').
se̮na-ллa ('in a word') > se̮noi-ллa ('with his words')
siллa-ллa ('on a bridge') > siлtoi-ллa ('on bridges')
o has been preserved anywhere in front of the plural -i- .
Diphtongs e̮a and iä and the plural -i- melt together into ī e.g. pimeä-llä ('on a dark (way)') > pim̆mī-llä ('on dark (ways)').
Short consonants were geminated in front of the long ī e.g. pimeä-llä ('on a dark (way)') > pim̆mī-llä ('on dark (ways)').
Western
In a group of villages the case endings are preceded by ai or äi ( depending in vowel harmony ) in plural
of some 2 syllable stems, if the stem vowel was i, u, o, e or e̮ : e.g. tšive-llä ('on a stone') > tšiväi-llä ('on stones'), лahze̮-лē̮ ('to a kid') > лahsai-лē̮ ('to kids'), pojo-лē̮ ('to a boy') > pojai-лē̮ ('to boys'), pilli-llä ('by a musical instrument') > pilläi-llä ('by instruments')
of some 3 syllable stems, if the stem vowel was i or o : e.g. ahvako-лē̮ ('to a perch') > ahvakkai-лē̮ ('to perches'), karjuši-лē̮ ('to a shepherd') > karjuššai-лē̮ ('to shepherds')
Diphtongs e̮a and iä and the plural -i- melt together into ī in ( Kattila and Pihlaala etc.) e.g. vaлke̮a-лē̮ ('onto a white (place)') > vaлkī-лē̮ ('onto white (places)'), pehmėä-llä ('on a soft (place)') > pehmī-llä ('on soft (places)').
All Votic (both eastern and western) dialects in contact with Soikkola ingrian dialect may use borrowed plural markers ( depending in vowel harmony ) -löi, -лoi or -läi, -лai (all four in the very same dialects) e.g. Mati dialectpüssü-löi-llä ('by guns'), jarvi-лoi-ллa ('on lakes'), Kõrvõttula dialectse̮tamehi-läi-l̄ ('by warriors'), vittso-лai-л̄ ('by twigs').
The plural diphthongsoi, e̮i, ai, äi are usually replaced with long vowels in unstressed syllables of plural partitive e.g. e̮hsa ('a tree branch') > e̮hsē̮ ('tree branches' - plural partitive), tšivi ('a stone') > tšiv̆vǟ ('stones' - plural partitive).
XIV Declension: -s stems ending with -iz in singular nominative have the same stem for plural and singular e.g. kallī-ллa ('on an expensive one') > kallī-ллa ('on expensive (things)').
