Etymology

Origin of transmission

1605–15; < Latin trānsmissiōn- (stem of trānsmissiō ) a sending across, equivalent to trānsmiss ( us ) (past participle of trānsmittere to send across) + -iōn- -ion. See trans-, mission

Explanation

Transmission is the act of transferring something from one spot to another, like a radio or TV broadcast, or a disease going from one person to another. The noun transmission comes from the Latin word transmissio, which means “sending over or across, passage.” The transmission of a message is the delivery of the message. Transmission can also be a communication sent out by radio or television, while the transmission of a disease is the passing of that virus or bacteria between people. A vehicle’s transmission is the part of the engine that uses the energy created by the burning fuel to make the axle turn.
