Classic car behind building is a representative example (9)
I believe the answer is:
archetype
'classic' is the definition.
(thesaurus)
'car behind building is a representative example' is the wordplay.
I cannot quite see how this works, but
an anagram of 'car' is 'arc' which is within the answer.
'example' could be 'type' (I've seen this in another clue) and 'type' is located in the answer.
The remaining letters 'he' is a valid word 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 archetype that I've seen before include "Model - perfect specimen" , "Very typical example" , "Very characteristic example" , "Original, prototype" , "Creepy hat (anag)" .)
