Speak about odd love for a sausage (7)
I believe the answer is:
saveloy
'for a sausage' is the definition.
(saveloy is a kind of sausage)
'speak about odd love' is the wordplay.
'speak' becomes 'say' (I've seen this before).
'about' means one lot of letters goes inside another.
'odd' is an anagram indicator.
'love' is an anagram of 'velo'.
'say' enclosing 'velo' is 'SAVELOY'.
(Other definitions for saveloy that I've seen before include "Type of sausage" , "One using brains originally" , "Highly seasoned pork sausage - love, say (anag)" , "Big sausage" , "Spicy sausage" .)
