After success in the examination I have resigned (7)
I believe the answer is:
passive
'resigned' is the definition.
(thesaurus)
'after success in the examination i have' is the wordplay.
'after' says to put letters next to each other.
'success in the examination' becomes 'pass' (I can't explain this - if you can you should give a lot more credence to this answer).
'i have' becomes 'I've' (contraction of 'I have').
'pass' next to 'ive' is 'PASSIVE'.
Can you help me to learn more?
(Other definitions for passive that I've seen before include "sort of voice" , "Slow to react" , "Inert, lethargic" , "Opposite of active" , "Not resisting" .)
