Etymology

Origin of transmit

First recorded in 1350–1400; Middle English transmitten, from Latin trānsmittere “to send across,” from trāns- trans- + mittere “to send”

Explanation

If you’re an international spy, you might transmit secret messages using a special code written in invisible ink. If you aren’t a spy, you could probably just use email. Whatever your circumstances, when you transmit information, you send. You can transmit things from person to person or from one thing to another. The airwaves can be used to transmit radio or TV signals, for example, and computers can transmit messages over a network. This verb often describes messages or data being sent, but you can also transmit ideas, beliefs, or attitude. In addition, transmit can describe the spread of disease, like mosquitoes that can transmit disease when they bite.
