Six technology words older than the technology
A computer was once a person who calculated, broadcasting scattered seed, a dashboard blocked carriage mud, and a monitor was someone who warned or advised.
New inventions often borrow old words. The choice gives an unfamiliar machine a familiar outline: it computes, points, warns, or spreads something widely. Years later, the machine becomes so familiar that the older picture fades.
A computer was a person
Computer appears in English centuries before the electronic device. It meant one who computes, a person paid to perform calculations. In astronomy, navigation, engineering, and government, human computers turned observations into tables. The machine did not invent the work's name; it inherited the worker's title.
To broadcast was to scatter seed
A farmer broadcasting seed casts it broadly over a field rather than placing it in rows. The agricultural adjective is recorded in the 18th century, and the verb followed. When radio began sending one signal toward a wide audience, the field supplied the metaphor. A podcast and a handful of grain now share the same basic motion.
A dashboard stopped flying mud
The original dashboard was a board or leather screen at the front of a horse-drawn carriage. It protected riders from mud and water dashed up by the horse's hooves. Early automobiles kept a panel in roughly the same location, then filled it with instruments. Software borrowed the word again for a screen that gathers important readings in one place.
A monitor was someone who warned you
Latin monitor meant one who reminds, advises, or warns. English first used the word for people who supervised or maintained order. It later named devices that watch conditions, then the screen on which a computer shows its work. The warning function still appears in a heart monitor; the display meaning has become broad enough to stand alone.
A tablet was already for writing
A medieval tablet was a small flat slab, often coated with wax so marks could be incised and smoothed away. The word also named stone inscriptions, medicinal lozenges, and pads of paper. Calling a thin, handheld computer a tablet was a revival of the oldest image, not a futuristic coinage: a portable surface made for reading and writing.
A mouse had a tail before it had a cable
The computer mouse took its name from physical resemblance. Early versions were small rounded boxes with a cord trailing behind like a tail. Wireless models have lost that feature, but the animal remains in the name and in the plural problem. In ordinary use, most speakers comfortably say mice for both.
Old words make new things less strange
Metaphor is a kind of interface. A dashboard tells you where to look. A monitor promises watchfulness. A tablet tells you to hold and write. The borrowed word helps people approach a new object before the object feels ordinary. Then, if the technology becomes dominant enough, it repays the loan by making the older meaning seem surprising. An obsolete technology can leave the same residue: stereotype, cliché, and boilerplate are all printer's equipment.
