"Rarely, or ever, did any maid or wife leave that court chaste," observed the sixteenth-century French ... (The New York Times)
I'm still not able to correctly use "ever" even if, when I read such word in a piece, I understand its meaning from the context.
On Merriam Webster Dictionary I read "ever" means "always", but I'm sure that "always" in the place of "ever" doesn't work in the sentence above: "Rarely, or always, did ...". Rather, "Rarely, or always, did ..." seems a nonsense.
Instead I'm less sure that replacing "ever" with "not always" doesn't function:"Rarely, or not always, did ...".
Also, another option that came to my brain is "not never", but it seems awkward: "?Rarely, or not never, did ...".
However, what it be the proprer form, I'm quite confused.
In reference to the sentence above, can anybody explain why "Rarely, or ever, ..." is correct, but "Rarely, or always, ...", "Rarely, or not always, ...", "Rarely, or not never, ..." are, eventually, not?
And, how about "rarely, or not ever, did ..."?
