Pharaoh has gold for teacher (5)
I believe the answer is:
tutor
'for teacher' is the definition.
(tutor is a kind of teacher)
'pharaoh has gold' is the wordplay.
'pharaoh' becomes 'tut' (Tutankhamun, the ancient Egyptian pharaoh).
'has' means one lot of letters go next to another.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'tut'+'or'='TUTOR'
(Other definitions for tutor that I've seen before include "trainer" , "Personal teacher" , "class leader" , "Individual teacher" , "He shows us the way" .)
