I think it's called a back formation, from an earlier word. It may be standard some day. Quite a few of words we use all the time started that way. Especially when no other simple word means the same thing. It's from surveillance of course, and I think whatever French verb that noun comes from is "survey" in English, but to say "I surveyed my girlfriend" would give entirely the wrong impression.

We've been friends for 20 years now, since we broke up. This guy came years later. She thought he was out with someone else.
I know he read the email btw. He seemed to open it 3 times over 4 or
5 days.He would only have to have an arrangement with another dentist or two. It wouldn't even have to be someone in the same practice**. And I assumed he did. I assumed that any decent dentist has that*** and later I saw t hat he had an emergency number on his webpage. But the number was, I guess, his number, not some service that would find the dentist on call.
**For example my brother is a radiologist, and even though it was known when he started that he would take vacations, iiuc when he went out of town, it was his responsibility to arrange with another radiologist to work for him. Fortunately there was one who didn't work full time because she had a young child, and she would work two weeks for him or two days, as she did sometimes for other radiologists in town. But not 50 weeks a year. ***which implies he's not a decent dentist, and he's not.Only that I don't know how to do it.
