It means "hole problems" for the rest of your days!

Sourcery?

A mage or a warlock?

same root as incubate. Originally it's a book bound in such as way as to look like an antique crib with straps to hold the baby in, but it has come to mean books printed between 1450 and 1500.

Most modern fantasy worldbuilders just grabbed the next synonym off the pile whenever they needed to subcategorize magic users further.
Q: what's the difference between a wizard and a sorcerer?
A: Depends on how Hasbro's lawyers are feeling today.

In which context?

The words literally just mean "miracle worker"

Not really. Or maybe it depends.

Reminds me of the fact that a lot of the terminology for magic is extremely coloured by how it's used in fantasy fiction and it might not be consistent with other fictional works, let alone how the words were/are used by magic practitioners. Fantasy authors have the benefit of just making the rules up.

(Perhaps most notable example is the term "witch" - pop culture defines that as female magic practitioners, but historically it was more of a gender neutral term in a lot of places. You know, kind of like the word "witchcraft" doesn't have gender connotations as such.)
