He gave people the law and doctors directions (5)
I believe the answer is:
moses
'he gave people the law' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'doctors directions' is the wordplay.
'doctors' becomes 'MOS' (an MO is a Medical Officer).
'directions' becomes 'es' (east and south - two directions).
'mos'+'es'='MOSES'
'and' is the link.
Can you help me to learn more?
(Other definitions for moses that I've seen before include "the tablet-taker?" , "He received the Ten Commandments on Mount Sinai" , "Liberator" , "Lawmaker" , "Leader of Jewish Exodus" .)
