Not co-operating in transition but it's over, as reported, see! (11)
I believe the answer is:
obstructive
'not co-operating' is the definition.
I can't judge whether this definition defines the answer.
'in transition but it's over as reported see' is the wordplay.
'in transition' indicates an anagram.
'as reported' indicates a 'sounds like' (homophone) clue.
'see' is a homophone of 'c'.
'but'+'its'+'over'+'c'='butitsoverc'
'butitsoverc' anagrammed gives 'OBSTRUCTIVE'.
Can you help me to learn more?
(Other definitions for obstructive that I've seen before include "Deliberately causing difficulties" , "Being deliberately difficult" , "Hindering" , "Causing deliberate difficulties" , "Intentionally unhelpful" .)
