To flourish means to grow strongly, thrive, and do really well. Plants flourish when they get enough sunlight and water, stretching tall with healthy leaves and bright flowers. People flourish when they're in the right environment for their talents and interests: a curious student might flourish in a school with great science labs, while an artistic kid might flourish when given time to draw and create.

The word suggests reaching full potential and showing real vitality. When something flourishes, it displays abundant energy and health. A friendship can flourish when both people make time for each other. A neighborhood garden flourishes when the community works together to tend it. A business flourishes when it grows and serves its customers well.

As a noun, a flourish can also mean a bold, sweeping gesture or movement. A conductor might finish a symphony with a flourish of the baton. A figure skater might end her routine with a dramatic flourish, arms spread wide. You might sign your name with a fancy flourish, adding an extra loop or swirl.

Notice how both meanings share a sense of boldness and abundance: whether it's growth reaching outward or a gesture that catches the eye, flourishing is about thriving openly and confidently.
