Quiet and initially wild like a sorcerer? (8)
I believe the answer is:
shamanic
'like a sorcerer?' is the definition.
'quiet and initially wild' is the wordplay.
'quiet' becomes 'sh'.
'initially' says to take the initial letters.
'wild' becomes 'manic' (I've seen this before).
The first letter of 'and' is 'a'.
'sh'+'a'+'manic'='SHAMANIC'
(Other definitions for shamanic that I've seen before include "Like a medicine man" , "Like a priest" , "charming doctor" .)
