What do football, radio, and email have in common? They all involve a receiver! A receiver is a position in American football, a part of a radio that translates the signal, or the person who gets the email you sent.
If you collect or accept something, you're a receiver. When an object is a receiver, it's either the part of a telephone that you listen to or the component of a stereo system, radio, or television that receives audio or video signals. Another kind of receiver is the North American football player who takes a position toward the edge of the field and who specializes in passing and catching the ball.
