Rule reminder

'Chi' = colui/colei/coloro che (person, no explicit antecedent). 'Quanto' = tutto quello che (thing/idea, no explicit antecedent). 'Dove' = in cui (place antecedent or free relative of place). 'Quando' = in cui (time antecedent or free relative of time). These pronouns introduce free relative clauses — clauses without an explicit antecedent noun.
