I’m a moving target (3)

Ross

I believe the answer is:

aim

'target' is the definition.
(both can mean a goal or purpose)

'i'm a moving' is the wordplay.
'moving' indicates an anagram.
'im'+'a'='ima'
'ima' with letters rearranged gives 'AIM'.

(Other definitions for aim that I've seen before include "intent" , "Try to achieve" , "Point towards a target, or have ambition" , "Plan" , "Attempt" .)

I've seen this clue in The Mirror.
