Run after a horse myself, to catch it (6)
I believe the answer is:
manage
'run' is the definition.
(thesaurus)
'a horse myself to catch it' is the wordplay.
I cannot quite see how this works, but
'a' could be 'an' and 'an' is located in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is present in the answer.
The remaining letters 'mag' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'after' is the link.
Can you help me to learn more?
(Other definitions for manage that I've seen before include "Run (a football team)" , "Be in overall control of" , "Run (eg, company)" , "Run, administer" , "Control; cope" .)
