Support fellow with twitch, being prescient (9)
I believe the answer is:
prophetic
'prescient' is the definition.
(thesaurus)
'support fellow with twitch' is the wordplay.
'support' becomes 'prop' (prop up can mean to support).
'fellow with' becomes 'he' (I can't explain this - if you can you should give a lot more credence to this answer).
'twitch' becomes 'tic' (tic is a kind of twitch).
'prop'+'he'+'tic'='PROPHETIC'
'being' acts as a link.
Can you help me to learn more?
(Other definitions for prophetic that I've seen before include "Divinatory, prescient" , "Foretelling events" , "divination" , "inspirational" , "Foreseeing future events" .)
