Object after silly performance (8)
I believe the answer is:
artefact
'object after silly performance' is the definition.
'artefact' can be an answer for 'object' (I've seen this before). I am not sure about the 'after silly performance' bit.
'after silly performance' is the wordplay.
'silly' indicates anagramming the letters.
'performance' becomes 'act' (act is a kind of performance).
'after' with letters rearranged gives 'artef'.
'artef'+'act'='ARTEFACT'
Can you help me to learn more?
(Other definitions for artefact that I've seen before include "hand-made thing" , "A result of craft" , "Man-made object, of archaeological interest say" , "Human-made article" , "Article of human workmanship" .)
