Protective describes someone or something that shields others from harm or danger. When a parent acts protective, they might hold their child's hand crossing a busy street or make sure they wear a helmet when riding a bike. A protective older brother might watch out for his younger sister on the playground, stepping in if other kids are being mean.

The word also describes physical things that guard against damage or injury. Protective gear for hockey includes padded gloves, shin guards, and a helmet with a face cage. A protective case for your phone keeps it safe if you drop it. Scientists wear protective eyewear in the lab to shield their eyes from chemicals.

People can be protective of things beyond physical safety too. A writer might feel protective of a story she's worked hard on, not wanting anyone to see it until it's finished. A collector might be protective of rare baseball cards, keeping them in special sleeves away from moisture and sunlight.

Sometimes people can be overprotective, meaning they try so hard to prevent harm that they don't let others take reasonable risks or learn from experience. Finding the right balance between protecting what matters and allowing growth takes wisdom and judgment.
