What is included is satisfactory (8)
I believe the answer is:
contents
'what is included' is the definition.
I can't tell whether this defines the answer.
'satisfactory' is the wordplay.
I cannot quite understand how this works, but
'satisfactory' could be 's' (abbreviation in education) and 's' is present in the answer.
The remaining letters 'content' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Other definitions for contents that I've seen before include "List of what's included" , "All that's contained" , "List of everything included" , "Makes satisfied - with ingredients?" , "constituents" .)
