Finnish Plural Forms for Nouns

Explore monikon muodostaminen (forming plurals) to talk about more than one in Finnish

In Finnish, plural forms for nouns are created by adding specific endings and following rules based on the noun's case and type. Unlike English, where adding -s or -es is often sufficient, Finnish plural forms depend on grammatical cases and vowel harmony. This guide will introduce you to the most common plural forms and how to use them.

Basic Plural Form: Nominative Plural

The nominative plural is used for the subject or when simply referring to "more than one" of something. To form the nominative plural, add -t to the noun's plural stem.

Steps to Form the Nominative Plural:

1. Identify the stem of the noun.

2. Add -t to the plural stem.

Examples:

1. talo (house) → talot – houses

2. auto (car) → autot – cars

3. kirja (book) → kirjat – books

4. lapsi (child) → lapset – children

---

Partitive Plural

The partitive plural is used to express incomplete actions, indefinite quantities, or objects in negative sentences. To form the partitive plural, add -ja/-jä, -ita/-itä, or -a/-ä to the plural stem, depending on the word's vowel harmony and type.

Examples:

1. kissa (cat) → kissoja – (some) cats

2. talo (house) → taloja – (some) houses

3. kukka (flower) → kukkia – (some) flowers

4. kala (fish) → kaloja – (some) fish

---

Genitive Plural

The genitive plural is used to indicate possession or relationships for plural nouns. To form it, add -en or -ten to the plural stem, sometimes with modifications to the stem itself.

Examples:

1. talo (house) → talojen – of the houses

2. auto (car) → autojen – of the cars

3. lapsi (child) → lasten – of the children

4. nainen (woman) → naisten – of the women

Other Plural Cases

Finnish uses many cases, and plurals adapt for each one. Here are examples of some common plural cases:

1. Inessive (Inside):

   • talossa (in the house) → taloissa (in the houses)

2. Elative (Out of):

   • talosta (out of the house) → taloista (out of the houses)

3. Illative (Into):

   • taloon (into the house) → taloihin (into the houses)

4. Adessive (On):

   • talolla (on the house) → taloilla (on the houses)

Irregular Plural Forms

Some Finnish nouns have irregular plural forms due to historical reasons or stem changes:

1. lapsi (child) → lapset (children)

2. vesi (water) → vedet (waters)

3. susi (wolf) → sudet (wolves)

---

Spoken Finnish Notes

In spoken Finnish, plural endings are often simplified, especially in casual contexts:

• Taloissa (in the houses) may sound like talol.

---

Quick Reference

• Nominative Plural: Add -t (e.g., talot – houses).

• Partitive Plural: Add -ja/-jä or -ita/-itä (e.g., taloja – (some) houses).

• Genitive Plural: Add -en/-ten (e.g., talojen – of the houses).

• Other Cases: Add case-specific endings to the plural stem.

Final Tips

1. Start with the nominative plural to get used to forming and recognizing basic plural forms.

2. Practice with common nouns to master the partitive plural and genitive plural forms.

3. Pay attention to vowel harmony and stem changes, as these can affect endings.

Finnish plural forms might seem complex, but with regular practice, you’ll start to recognise patterns and use them with ease.
