In the old days you only got 1 stop adjustments. That's indeed where we got the term "stop" from. It was the clicks on your old shutter speed dial and your old aperture ring. Now our "clicks" control 1/3 stops.

I'm pretty sure that "stop" originally referred to metal plates that stopped the light from entering the lens.

Here's a reference to "stop" being used in print in 1867...

Thanks for the correction!
