Coy nurse turned out to be centre of attention (8)
I believe the answer is:
cynosure
'to be centre of attention' is the definition.
(I've seen this before)
'coy nurse turned' is the wordplay.
'turned' indicates anagramming the letters.
'coy'+'nurse'='coynurse'
'coynurse' anagrammed gives 'CYNOSURE'.
'out' acts as a link.
(Other definitions for cynosure that I've seen before include "Irresistible sight" , "that attracts attention" , "Focus of attention" , "major attraction" , "Little Bear" .)
