Published work showing eclipse (5)
I believe the answer is:
outdo
'eclipse' is the definition.
(I've seen this before)
'published work' is the wordplay.
'published' becomes 'out' (I've seen this in another clue).
'work' becomes 'do' (synonyms).
'out'+'do'='OUTDO'
'showing' is the link.
(Other definitions for outdo that I've seen before include "Surpass - overshadow - excel" , "Be better in performance (than another person)" , "Cap" , "Br superior to (someone)" , "Perform better than, be superior to" .)
