Policeman runs past where skaters relax (7)
I believe the answer is:
officer
'policeman' is the definition.
(synonyms)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for officer that I've seen before include "Member of the armed forces in position of authority" , "Commissioned rank" , "Maybe society treasurer" , "Serviceman (or woman) of rank" , "Person with authority or command" .)
