Shockingly, I retain passivity (7)

Ross

I believe the answer is:

inertia

'passivity' is the definition.
(lack of movement)

'shockingly i retain' is the wordplay.
'shockingly' is an anagram indicator.
'i'+'retain'='iretain'
'iretain' anagrammed gives 'INERTIA'.

(Other definitions for inertia that I've seen before include "Idling" , "Motionlessness" , "Sloth; inactivity" , "Unwillingness to move" , "Change-resisting tendency" .)

I've seen this clue in The Times.
