✦Grammar Breakdown

Dipendere (dipende)
The verb *dipendere* is used in the third‑person singular present; it always takes the preposition *da* to introduce the cause or condition.
Quante (interrogative adjective)
*Quante* agrees in gender and number with the noun it modifies; here it is feminine plural to match *persone*.
Ci sono (existential construction)
The phrase *ci sono* means “there are” and is used for plural subjects; for a singular you would say *c’è*.
In casa (prepositional phrase)
*In* + *casa* literally means “in the house/home”; it is the most common way to talk about who is present at home.

✕Common Mistakes
Dipende da quante persone c’è in casa.
Use *c’è* only for singular subjects; the sentence talks about multiple people, so *ci sono* is required.
Dipende da quanti persone ci sono in casa.
*Quanti* is masculine; the noun *persone* is feminine, so the correct form is *quante*.
Dipende che quante persone ci sono in casa.
*Da* is the correct preposition after *dipendere*; *che* would be a grammatical error.

Cultural Tip
In Italy, family gatherings are common, and the size of a household often influences daily routines such as meal planning, heating, and even the timing of TV programs. When speaking to Italians, using *casa* feels informal and friendly; for a more formal context you could say *abitazione* or *residenza*.
