Adopt sure reform - it's extended far and wide (9)
I believe the answer is:
outspread
'extended far and wide' is the definition.
'outspread' can be an answer for 'extended' (I've seen this before). I'm not sure about the 'far and wide' bit.
'adopt sure reform' is the wordplay.
'reform' is an anagram indicator (letters in a new form).
'adopt'+'sure'='adoptsure'
'adoptsure' is an anagram of 'OUTSPREAD'.
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for outspread that I've seen before include "Fully extended" , "Wide apart" , "Scattered" .)
