megaphone
Other forms: megaphones
A megaphone is a cone-shaped amplifier you can use to make your voice louder. You can bring a megaphone to a football game, but leave it at home if you are headed to a dinner party.
Megaphones are useful, portable devices for someone who's guiding a group of protesters, for a movie director who's working with a lot of actors on a large set, or for cheerleaders who want their voices to carry over the roar of a crowd of football fans. Thomas Edison invented the megaphone, and he probably named it too: it combines the Greek megas, "great," with phone, "voice."
