Take strong objection to marriage of Ted and Tess (7)
I believe the answer is:
detests
'take strong objection to marriage' is the definition.
I can't tell whether this defines the answer.
'of ted and tess' is the wordplay.
'of' indicates an anagram (the answer comes from or 'of' the letters).
'and' says to put letters next to each other.
'ted' after 'tess' is 'tessted'.
'tessted' anagrammed gives 'DETESTS'.
Can you help me to learn more?
(Other definitions for detests that I've seen before include "Abhors" , "Cordially loathe" , "Loathes" , "Abominates" , "Hates" .)
