Doctor initially assists German dissecting aged script consultant (10)
I believe the answer is:
dramaturge
'script consultant' is the definition.
The definition suggests a singular noun which matches the answer.
'doctor initially assists german dissecting aged' is the wordplay.
I cannot really understand how this works, but
'doctor' could be 'dr' (abbreviation) and 'dr' is located in the answer.
'german' could be 'g' (abbreviation) and 'g' is found within the answer.
'aged' could be 'mature' (similar in meaning) and 'mature' is located in the remaining letters.
A single letter 'a' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dramaturge that I've seen before include "one's ended up in theatre" , "playwright" , "specialist in theatre" .)
