Absolutely continuous. This is slightly more restrictive than just
having a continuous distribution function, effectively meaning that
the density can be defined (with respect to Lebesgue measure on some
interval, usually).

Counterexamples are pathological, the sort of thing you challenge 2nd
year math/stat students to think up, but I can't say that I can
remember what they'd look like.
