Supporter encountering nuclear Dusseldorf? (6)
I believe the answer is:
propel
'supporter encountering nuclear dusseldorf?' is the definition.
I can't tell whether this defines the answer.
'supporter encountering nuclear dusseldorf?' is the wordplay.
'supporter' becomes 'prop' (I've seen this before).
'encountering' is a charade indicator (letters next to each other).
'nuclear dusseldorf?' becomes 'el' (I can't justify this - if you can you should give a lot more credence to this answer).
'prop'+'el'='PROPEL'
Can you help me to learn more?
(Other definitions for propel that I've seen before include "Push forwards" , "Cause to move forward with force" , "Launch" , "Give impetus to" , "Drive or push forward as with oars" .)
