@alexbuzzbee first off, I believe there's a lot of fuss over theoretical terminology that's mostly irrelevant.
That said, microkernel is better understood as "not monolithic" vs any commentary on size. Thus, no scale of micro, milli, mini, nano, etc.
Hybrid just means monolithic kernel that maybe runs some stuff in a different process. I think the term is the result of "but, look, this component isn't in the same address space, so therefore well actually technically it's not monolithic."
Unless you're taking an exam, I'd say none of this matters. If you are taking an exam, just repeat whatever the professor tells you to. :)
