Listing of forbidden language about love (10)
I believe the answer is:
tabulation
'listing' is the definition.
(thesaurus)
'of forbidden language about love' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is found within the answer.
'forbidden' could be 'tabu' (synonyms) and 'tabu' is located in the answer.
'language' could be 'latin' (Latin is an example) and 'latin' is found within the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for tabulation that I've seen is " Putting into columns".)
