Works at suppressing love, leading to insignificant future (7)
I believe the answer is:
destiny
'future' is the definition.
(thesaurus)
'works at suppressing love leading to insignificant' is the wordplay.
I cannot really understand how this works, but
'at' could be 'in' (synonymous in some cases - eg at school, in school) and 'in' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for destiny that I've seen before include "Ultimate fate" , "Kismet, fate" , "must?" , "Fortune" , "The future as arranged by fate" .)
