Ogni

Ogni is an Italian determiner meaning "every" or "each." It is placed before a singular noun to indicate that a property or action applies to all members of a group. Ogni is used with singular nouns and is not assigned a plural form; it is not used with plural nouns directly (for plural, other expressions such as tutti or ciascuno may be used).

Grammatical notes: Ogni is invariable for gender and number. It normally precedes the noun: ogni giorno, ogni persona, ogni libro. It also appears in fixed phrases such as ogni volta (every time). Because of its invariable nature, it does not change to agree with the noun that follows.

Ogni vs ognuno: Ogni is a determiner, while ognuno (ognuno, ognuna, ognuno) is a pronoun meaning "everyone" or "each person." For example, Ogni studente ha una copia del libro, while Ognuno ha i propri sogni expresses a statement about individuals within a group. Ciascuno is another pronoun with a similar meaning, often used in slightly more formal or literary contexts.

Etymology: Ogni derives from the Latin omnis or omne meaning "all" or "every." The form has evolved in Italian to function as a determiner that attaches to singular nouns.

See also: ciascuno, ognuno, ciascuna, ognuna, tutti, ogni cosa.

Examples:

- Ogni giorno porto una borraccia d'acqua.

- Ogni libro su quella mensola è stato scritto da un autore diverso.

- Ogni volta che ci provi, impari qualcosa.
