Moving small objects (7)
I believe the answer is:
motives
'objects' is the definition.
(both can mean goals or plans)
'moving small' is the wordplay.
'moving' becomes 'motive' (motive can mean moving or in motion).
'small' becomes 's' (abbreviation - e.g. clothes size).
'motive'+'s'='MOTIVES'
(Other definitions for motives that I've seen before include "They're why" , "Reasons for action" , "inducements" .)
