Heads for colleges in hills beyond park (7)
I believe the answer is:
rectors
'heads for colleges in' is the definition.
I can't judge whether this defines the answer.
'hills beyond park' is the wordplay.
'hills' becomes 'tors' (tor is a kind of hill).
'beyond' is a charade indicator (letters next to each other).
'park' becomes 'rec' (short for recreation ground).
'tors' put after 'rec' is 'RECTORS'.
Can you help me to learn more?
(Other definitions for rectors that I've seen before include "Clergymen" , "ministers" .)
