Usage notes
- Costui is a formal or literary demonstrative meaning "this man/person"; in everyday speech, use questo, questo qui, or lui instead.
- It often sounds distancing, judgmental, or ironic, especially when referring to someone just mentioned.
- Use costui for masculine singular only. Feminine is costei; plural forms are costoro, but all are quite rare today.
