Flatter

'Flatter' means to say nice things to someone to make them feel good about themselves. It's like when your mom tells you that you're a very good helper when you help her clean up your toys. That is a compliment which makes you feel good about doing something helpful. Flattery is when someone gives you a compliment that's designed to make you feel good about yourself. It's important to understand that sometimes people use flattery to get something they want from you, like a favor or something you own. But it's also okay to give compliments and make people feel good about themselves, as long as it's genuine and not just to get something from them.
