Etymology

Origin of dial

First recorded in 1400–50; Middle English dial, diel,dyal “instrument for telling time by the sun's shadow,” from Old French dyal, from Medieval Latin diālis “daily” ( Latin di(ēs) ) “day” + -ālis adjective suffix; -al ¹ )

Explanation

A dial is a circle that has a series of numbers or marks representing numbers, like the dial of a clock face, a compass, or an old-fashioned telephone. If you have a watch that glows in the dark, it's the dial you can see even in a dark movie theater. Old telephones and televisions both have dials — the first has numbers from zero to nine in a circle, and the latter has a round disc for changing channels. When you call someone, you can say that you dial their number. In fact, people tend to use the word dial when they use a phone, even if they're pushing buttons or tapping a touch screen. The Latin root is dialis, "daily," and the earliest dial was a sundial.
