repeated
Happening again and again in the same way.
Repeated means done, said, or happening more than once. When your teacher gives repeated warnings about talking in class, she's told you multiple times to be quiet. When a song has a repeated chorus, the same words and melody come back again and again.
The word emphasizes that something keeps occurring in the same way. A scientist doing repeated experiments runs the same test multiple times to make sure the results are reliable. A basketball player practices repeated free throws, shooting from the same spot over and over to build consistency. When doctors see repeated symptoms in a patient, they notice the same problems appearing again and again, which helps them figure out what's wrong.
Repeated can describe patterns in nature too: the repeated hexagons in a honeycomb, the repeated beats of your heart, or the repeated cycle of day turning into night. Sometimes repeated things become predictable or even boring (like hearing the same joke over and over), but repetition also creates mastery, rhythm, and reliability.
