Television: "seeing what is happening at a place concealed from the observer's eyes"
I like this definition of “television” from the Oxford English Dictionary, quoted on etymonline.
1907: the action of seeing by means of Hertzian waves or otherwise, what is existing or happening at a place concealed or distant from the observer’s eyes [OED]
It makes it sound more mystical. Compared to how we currently think about it anyway.
Tele - comes from the Greek meaning ”far off, afar, at or to a distance”.
