Very good reason for parmesan I typically included (6)
I believe the answer is:
sanity
'very good reason' is the definition.
'sanity' can be an answer for 'reason' (I've seen this before). I'm not certain of the 'very good' bit.
'parmesan i typically included' is the wordplay.
'included' indicates the answer is hidden within the clue (I've seen 'include' mean this).
'SANITY' is hidden within 'parmesan i typically'.
'for' is the link.
Can you help me to learn more?
(Other definitions for sanity that I've seen before include "State of having a healthy mind" , "Reason, condition of being compos mentis" , "Rationality" , "Soundness of mind" , "Sound powers of mind" .)
