Something a loader could do (6)
I believe the answer is:
reload
'do' is the definition.
Although both the answer and definition are verbs in their base form, I don't see how one could define the other.
'something a loader' is the wordplay.
'loader' can be anagrammed to 'RELOAD'.
But, I'm not sure how this is indicated.
'could' acts as a link.
Can you help me to learn more?
(Other definitions for reload that I've seen before include "Fill (a gun) again" , "Encumber again" , "Put more bullets in" , "Put new ammunition in gun" , "Put bullet in gun - again" .)
