Element found in artefact, originally (6)
I believe the answer is:
factor
'element' is the definition.
(I know that element can be written as factor)
'in artefact originally' is the wordplay.
'in' indicates the answer is hidden within the clue.
'FACTOR' is hidden in the letters of 'artefact originally'.
'found' acts as a link.
(Other definitions for factor that I've seen before include "Influencing circumstance" , "Circumstance that contributes towards a result" , "Contributory influence; business agent" , "Thirteen is one of fifty two" , "Component, element" .)
