indulge

Indulge means to do something that you really enjoy or like a lot. For example, when you eat a big bowl of ice cream because it makes you happy, you are indulging in something sweet and delicious.

Indulge can also mean to let someone have or do something that they want, even if it's not good for them. For example, if your mom lets you stay up late to watch your favorite TV show, she is indulging you by giving you a special treat.
