Australian dame Burt managed to obscure (9)
I believe the answer is:
adumbrate
'obscure' is the definition.
(I've seen this before)
'australian dame burt managed' is the wordplay.
'australian' becomes 'A' (common abbreviation).
'managed' indicates an anagram.
'dame'+'burt'='dameburt'
'dameburt' anagrammed gives 'dumbrate'.
'a'+'dumbrate'='ADUMBRATE'
'to' acts as a link.
(Other definitions for adumbrate that I've seen before include "sketch" , "Give a faint idea of; overshadow" , "Depict in outline" , "Indicate or describe in a general way" , "Faintly indicate" .)
