Strange love for a Doctor of Divinity (3)
I believe the answer is:
odd
'strange' is the definition.
(I've seen this in another clue)
'love for a doctor of divinity' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'for' says to put letters next to each other.
'a doctor of divinity' becomes 'DD' (synonyms).
'o'+'dd'='ODD'
(Other definitions for odd that I've seen before include "Peculiar or eccentric" , "Left over" , "Eccentric or unpaired" , "Unusual, strange" , "Unmatched" .)
