Something made café tart peculiar (8)
I believe the answer is:
artefact
'something made' is the definition.
I can't tell whether this defines the answer.
'cafe tart peculiar' is the wordplay.
'peculiar' indicates an anagram (a peculiar or strange ordering of the letters).
'cafe'+'tart'='cafetart'
'cafetart' anagrammed gives 'ARTEFACT'.
Can you help me to learn more?
(Other definitions for artefact that I've seen before include "Article of human workmanship" , "Item made by human" , "Man-made item" , "not natural" , "Made object" .)
