Support this writer has to be rebellious? (7)
I believe the answer is:
restive
'rebellious?' is the definition.
(thesaurus)
'support this writer has to' is the wordplay.
'support' becomes 'rest' (e.g. a shoulder rest is a support for shoulder).
'this writer' becomes 'I' (the person writing the crossword).
'has to' becomes 've' (I can't explain this - if you can you should believe this answer much more).
'rest'+'i'+'ve'='RESTIVE'
'be' is the link.
Can you help me to learn more?
(Other definitions for restive that I've seen before include "Resisting control, nervous or impatient" , "It veers around, resisting control" , "Unable to stay still" , "Impatient of authority" , "Uneasy, nervous" .)
