I am Victorian, perhaps, joining Northern Territory. Unwise? (9)
I believe the answer is:
imprudent
'unwise?' is the definition.
('imprudent' can be similar in meaning to 'unwise')
'i am victorian perhaps joining northern territory' is the wordplay.
'i am' becomes 'I'm' (contraction).
'victorian perhaps' becomes 'prude' (I am not sure about this - if you are sure you should believe this answer much more).
'joining' is a charade indicator (letters next to each other).
'northern territory' becomes 'nt'.
'im'+'prude'+'nt'='IMPRUDENT'
Can you help me to learn more?
(Other definitions for imprudent that I've seen before include "Reckless" , "Rash, lacking discretion" , "Lacking in good sense or caution" , "Unwise" , "not wise" .)
