Abound means to exist in large numbers or amounts. When something abounds, there's plenty of it everywhere you look.

A forest might abound with wildflowers in spring, meaning you see them covering the ground in every direction. A successful bakery might abound with the delicious smells of fresh bread and pastries. After a rainstorm, puddles abound on the playground.

The word captures a sense of overflowing abundance, like nature showing off. You might read that a coral reef abounds with colorful fish, or that a good library abounds with fascinating books. Teachers sometimes say that opportunities abound for students who work hard and stay curious, meaning chances for learning and growth are everywhere if you pay attention.

Notice how abound often pairs with “with”: something abounds with whatever fills it up.
