To thrive is to do well or flourish. If your new cookie delivery business thrives, you'll be rolling in dough — not literally, of course.
The verb thrive means to flourish or grow vigorously, and it can be applied to something like a business or to the health of someone or something. Plants can thrive in a greenhouse, and children can thrive if they eat well and exercise. To thrive on or in something can also be used more figuratively — people can thrive on music, listening to their favorite songs all day and others can thrive on art, visiting their favorite galleries and museums.
