Relative pronoun CUI

“…è il giorno in cui sono morti…”
(it is the day in which died…)

“Cui” is a relative pronoun in Italian that is used to introduce a subordinate clause and to refer to a noun or a pronoun that comes before it.
It is used instead of “che” (that, which) when following a preposition.

For example, in the sentence above, ”in cui” means “in which” or “on which” in English. It introduces a relative clause and links it to the noun “giorno” (day) that was previously mentioned.
Here are more examples:

– “Nella città IN CUI abito ci sono molti cinema”
= There are a lot of cinemas in the town IN WHICH I live

– “L’amico A CUI scrivo si chiama Luca”
= The friend TO WHOM I’m writing is called Luca

– “La casa IN CUI abito è carina”
= The house IN WHICH I live is cozy

In the sentence above, ”in cui” means “in which” or “on which” in English. It introduces a relative clause and links it to the noun “giorno” (day) that was previously mentioned.
