Something made in that cafe traced back (8)
I believe the answer is:
artefact
'something made' is the definition.
I can't tell whether this definition defines the answer.
'in that cafe traced back' is the wordplay.
'in' indicates a hidden word.
'back' says the letters should be written in reverse.
'tcafetra' is hidden in the letters of 'that cafe traced'.
'tcafetra' back-to-front is 'ARTEFACT'.
Can you help me to learn more?
(Other definitions for artefact that I've seen before include "Made object" , "A result of craft" , "Thing made by human workmanship" , "Article of human workmanship" , "Something man made" .)
