Learn Italian: A Marco non piace chi rischia troppo. - Marco does not like people who risk too much.

In Italian, chi is not just for questions. When used in a statement, it acts as a generalized pronoun meaning "whoever," "anyone who," or "the people who."

If chi means "people who," why are the verbs piace and rischia in the singular?

Even when chi refers to a group of people in general, it is always grammatically singular in Italian. That is why it takes the third-person singular verbs rischia and piace.

Why is there an A before Marco?

The verb piacere works differently than "to like" in English; it literally means "to be pleasing to." So, this sentence translates literally as "To Marco is not pleasing whoever risks too much."

What is the subject of piace here?

The entire phrase chi rischia troppo (whoever risks too much) acts as the subject. Since chi is treated as singular, it makes the whole phrase a singular subject, which is why we use piace instead of the plural piacciono.
