Sausage involves a sort of love, say (7)
I believe the answer is:
saveloy
'sausage' is the definition.
(I know that Saveloy is a type of sausage)
'of love say' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'love'+'say'='lovesay'
'lovesay' anagrammed gives 'SAVELOY'.
'involves a sort' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for saveloy that I've seen before include "Highly seasoned pork sausage - love, say (anag)" , "Type of sausage" , "Big sausage" , "One using brains originally" , "Spicy sausage" .)
