Etymology

It is formed from English transmit + -er.[1][2][3][4][5] The verb transmit, recorded from about 1400,[4] comes through Middle English transmitten from Latin trānsmittō (“to send across, transfer”), from trāns- (“across”) and mittō (“to send”).[4][6][1]

Earliest recorded meaning

A person or thing that transmits something: 1727, in Richard Savage's The Bastard.[1][4][2] Johnson (1773) defined it simply as "one that transmits".[7]

Semantic evolution

From 1844 the word named the sending part of a telegraph, and later of a telephone, as opposed to the receiver.[1][4] Etymonline dates the sense "apparatus for sending out radio or television signals" to 1934.[4] In physiology it has been used since 1930 for a neurotransmitter.[1]
