means the act of doing or saying the same thing again, often many times, whether to practice, emphasize, or simply because it recurs.

from From Latin repetitio, a noun built on repetere, "to seek again" or "to attack again" — a fusion of re- ("again") and petere ("to aim at, reach toward, seek"). That same petere fathered a sprawling family: petition, appetite, compete, impetus — all of them straining toward something. Repetition is simply the reaching done over and over, until the hand learns the way by heart.
