The pronoun "cui" is used in Italian to refer to a person or thing that has been previously mentioned or is known from the context. It is often used after prepositions, such as "a cui" (to whom/which) or "di cui" (of whom/which), to indicate possession, location, or other relationships.
For example, in the sentence "Il libro di cui ti ho parlato" (The book of which I told you), the pronoun "cui" is used to refer to the book that was previously mentioned. In this case, it indicates possession and is preceded by the preposition "di" (of).
It's important to note that the form of the pronoun "cui" changes depending on its role in the sentence. It can be masculine, feminine, singular, or plural. The correct form of "cui" should agree with the noun it refers to.
