Current model arranged visit for a militant organiser (8)
I believe the answer is:
activist
'a militant organiser' is the definition.
I can't judge whether this defines the answer.
'current model arranged visit' is the wordplay.
'current' becomes 'ac' (alternating current).
'model' becomes 't' (Ford Model T car).
'arranged' indicates an anagram.
'visit' anagrammed gives 'ivist'.
'ac'+'t'+'ivist'='ACTIVIST'
'for' is the link.
Can you help me to learn more?
(Other definitions for activist that I've seen before include "Vigorous political campaigner" , "Committed campaigner" , "Advocate for action" , "forceful person" , "One who plays a vigorous role, especially in politics" .)
