To be reserved means to be someone who is not openly expressive of feelings or opinions and tends to keep thoughts, emotions, and personal information to oneself. Reserved individuals often prefer solitude or small, close relationships rather than being the center of attention or socially outgoing. They are usually calm, introspective, cautious in social interactions, and emotionally stable, often taking time to think before speaking or acting. Additionally, "reserved" can also mean something kept for a particular person or purpose, like a reserved seat or space.
