Why common collector amplifier is known aa emitter follower, Electrical Engineering

Q. Why a common collector amplifier is called an emitter follower?

        When the input voltage goes through its positive half cycle, the output voltage is also seen to go through its positive half cycle. In other words the output and input are in phase with each other. Besides the magnitude of the output and input are about the same. Thus the emitter voltage (i.e. output voltage) closely follows the input voltage. Hence the name emitter follower.
