What does rotate mean in aviation?

In aviation, "rotate" refers to the action of lifting an aircraft's nose off the ground during takeoff. It occurs when the pilot pulls back on the control yoke or stick at a specific speed, allowing the aircraft to transition from the ground to the air. This maneuver is critical for achieving the proper angle of attack for takeoff. The rotation speed, or Vr, is determined by factors such as aircraft weight and runway conditions.
