Turning taken by an American car (6)
I believe the answer is:
street
'turning taken by an american car' is the definition.
I can't judge whether this defines the answer.
'turning taken by an american car' is the wordplay.
'turning' says the letters should be written backwards.
'taken by' is an insertion indicator.
'an american' becomes 'teers' (I can't justify this - if you can you should believe this answer much more).
'car' becomes 't'.
'teers' placed around 't' is 'teerts'.
'teerts' in reverse letter order is 'STREET'.
Can you help me to learn more?
(Other definitions for street that I've seen before include "City thoroughfare" , "See 17" , "See 7" , "See 1 Down" , "Paved road" .)
