Answer doctor in hospital department with description of traffic light, perhaps (5)
I believe the answer is:
amber
'department with description of traffic light perhaps' is the definition.
I can't judge whether this definition defines the answer.
'answer doctor in hospital' is the wordplay.
'answer' becomes 'a' (abbreviation eg in Q and A).
'doctor' becomes 'mb' (Bachelor of Medicine, Medicinae Baccalaureus).
'in hospital' becomes 'er' (I've seen this in other clues).
'a'+'mb'+'er'='AMBER'
Can you help me to learn more?
(Other definitions for amber that I've seen before include "Orange traffic light" , "Stone" , "Brownish yellow" , "Medium to dark brownish-yellow colour" , "gemstone" .)
