Temple icon being forged, not yet finished (10)
I believe the answer is:
incomplete
'not yet finished' is the definition.
(I've seen this before)
'temple icon being forged' is the wordplay.
'being forged' indicates anagramming the letters.
'temple'+'icon'='templeicon'
'templeicon' anagrammed gives 'INCOMPLETE'.
(Other definitions for incomplete that I've seen before include "Unfinished" , "not done" , "Lacking" , "Not yet finished" , "not sufficient" .)
