Standing still though not against reform (10)
I believe the answer is:
stagnation
'standing still' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'not against reform' is the wordplay.
'reform' indicates anagramming the letters (letters in a new form).
'not'+'against'='notagainst'
'notagainst' anagrammed gives 'STAGNATION'.
'though' is the link.
Can you help me to learn more?
(Other definitions for stagnation that I've seen before include "Inactivity" , "Lack of movement or growth" , "State of little activity" , "Process of reducing activity" , "State of lethargy" .)
