Old master got rash over middle of thigh — whom to consult? (13)
I believe the answer is:
dermatologist
'whom to consult?' is the definition.
I can't judge whether this definition defines the answer.
'old master got rash over middle of thigh' is the wordplay.
'rash' is an anagram indicator (a reckless or careless ordering of the letters).
'over' means one lot of letters goes inside another.
'middle of' says to take the centre.
The central letter of 'thigh' is 'i'.
'old'+'master'+'got'='oldmastergot'
'oldmastergot' anagrammed gives 'dermatologst'.
'dermatologst' going around 'i' is 'DERMATOLOGIST'.
Can you help me to learn more?
(Other definitions for dermatologist that I've seen before include "Expert in skin disorders" , "Skin disorder expert" , "medical consultant needed" , "Skin disease expert" , "Skin specialist" .)
