A petal is a part of a flower. Most flowers have a ring of brightly colored petals surrounding the center part of the blossom.
Petal comes from the Greek word petalon, meaning "leaf, thin plate." A petal is the lovely colorful leaf-like ring around the center of the flower, a thin plate for a fairy. The petals make up a flower’s corolla, surrounding the center. You can rip them off one by one as you say, “She loves me, she loves me not” until the last petal is picked. She loves me!
