Origin of tuner
1570–80; 1905–10 tuner for def. 2; tune + -er 1
Explanation
A tuner is an electronic device that receives signals and allows you to listen to the radio or watch television. Another kind of tuner is used to adjust the pitch of a musical instrument. One kind of tuner can receive digital signals so you can watch television, and another kind is built into your car radio. A person can be a tuner too, such as an expert who makes adjustments to a piano's strings until the pitch is correct. There are also small electronic tuners that attach to an instrument like a guitar. Before it meant "instrument adjuster," a tuner was a "musician or singer."
