Secretary gets SLR finally, chaps coming round mostly say cheese (8)
I believe the answer is:
parmesan
'cheese' is the definition.
(I know that Parmesan is a type of cheese)
'secretary gets slr finally chaps coming round mostly' is the wordplay.
I cannot really see how this works, but
'secretary' could be 'pa' (abbreviation for personal assistant) and 'pa' is located in the answer.
This explanation may well be incorrect...
'say' acts as a link.
(Other definitions for parmesan that I've seen before include "Italian cheese for spearman" , "Hard dry Italian cheese" , "Dry sharp-flavoured Italian cheese" , "Hard dry cheese, often grated" , "Cheese for grating" .)
