Targets, as I'm moving (4)
I believe the answer is:
aims
'targets' is the definition.
('aim' can be a synonym of 'target')
'as i'm moving' is the wordplay.
'moving' indicates an anagram.
'as'+'im'='asim'
'asim' is an anagram of 'AIMS'.
(Other definitions for aims that I've seen before include "Sets sight on, having ambitions" , "Targets and ambitions" , "Objectives, purposes" , "objects" , "Proposes or intends" .)
