Swearing about regular instalments of satire not being easy to get (8)
I believe the answer is:
abstruse
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for abstruse that I've seen before include "Obscure or recondite" , "Difficult to penetrate or understand" , "Esoteric" , "Difficult to understand, obscure" , "Strange busts are difficult to understand" .)
