Make for a master (4)
I believe the answer is:
head
I believe this is a double definition.
'make for' is the first definition.
(thesaurus)
'a master' is the second definition.
(I know that master can be written as head)
(Other definitions for head that I've seen before include "Skull" , "School boss" , "Edible part of cabbage" , "Lead - school principal" , "Source of river, leader" .)
