King with ecstasy put on suits, creating responses (9)
I believe the answer is:
reactions
'responses' is the definition.
(I know this)
'king with ecstasy put on suits' is the wordplay.
'king with' becomes 'r' (I can't justify this - if you can you should give a lot more credence to this answer).
'ecstasy' becomes 'E' (informal term for the drug).
'put on' means one lot of letters go next to another (some letters go on or after others).
'suits' becomes 'actions' ('action' can be a synonym of 'suit').
'r'+'e'+'actions'='REACTIONS'
'creating' is the link.
Can you help me to learn more?
(Other definitions for reactions that I've seen before include "What you may get with chemicals" , "Newton's law of motion says all actions have them" , "Takes" , "Responses, chemical perhaps" , "Mental or physical responses" .)
