Noun Number: Singular and Plural Forms

In Italian, all nouns have a number, either singular or plural. The singular form refers to one item, while the plural form refers to two or more items. To form the plural of Italian nouns, we need to change the ending of the noun. The ending depends on the gender and the category of the noun.

Masculine Nouns

1. Masculine nouns ending in -o: Most masculine nouns end in -o in the singular form. To make them plural, replace the -o with an -i. For example:

• libro (book) becomes libri (books)
• tavolo (table) becomes tavoli (tables)

1. Masculine nouns ending in -e: Some masculine nouns end in -e in the singular form. To make them plural, replace the -e with an -i. For example:

• padre (father) becomes padri (fathers)
• albero (tree) becomes alberi (trees)

Feminine Nouns

1. Feminine nouns ending in -a: Most feminine nouns end in -a in the singular form. To make them plural, replace the -a with an -e. For example:

• casa (house) becomes case (houses)
• torta (cake) becomes torte (cakes)

1. Feminine nouns ending in -e: Some feminine nouns end in -e in the singular form. To make them plural, replace the -e with an -i. For example:

• chiave (key) becomes chiavi (keys)
• voce (voice) becomes voci (voices)

Irregular Plurals and Exceptions

As in any language, there are exceptions to the general rules when forming plural nouns in Italian. Here are some of the most common irregular plurals and exceptions:

1. Nouns ending in -ca and -ga: To form the plural of nouns ending in -ca or -ga, add an -h before the plural ending. For example:

• amica (female friend) becomes amiche (female friends)
• collega (colleague) becomes colleghi (colleagues)

1. Nouns ending in -io: Some nouns ending in -io have an irregular plural form. If the stress falls on the -i, the plural is formed by simply dropping the -o. If the stress falls on another syllable, the plural is formed by replacing the -o with an -i. For example:

• principio (principle) becomes principi (principles)
• negozio (shop) becomes negozi (shops)

1. Invariable nouns: Some nouns do not change in the plural form. These include nouns ending in an accented vowel, nouns ending in a consonant, and some foreign loanwords. For example:

• città (city) remains città (cities)
• computer (computer) remains computer (computers)

1. Irregular plurals: A few nouns have irregular plural forms that do not follow the usual rules. For example:

• uomo (man) becomes uomini (men)
• dio (god) becomes dei (gods)

Noun Agreement with Adjectives and Articles

When using plural nouns in Italian, it is essential to ensure that adjectives and articles agree in gender and number. For example:

• il libro interessante (the interesting book) becomes i libri interessanti (the interesting books)
• la casa grande (the big house) becomes le case grandi (the big houses)
