Those introducing the Oscars' newest yearly award (4)
I believe the answer is:
tony
'award' is the definition.
(I've seen this in another clue)
'those introducing the oscars' newest yearly' is the wordplay.
'those introducing' suggests taking the first letters (the letters which begin or introduce the words).
The first letters of 'the oscars newest yearly' is 'TONY'.
(Other definitions for tony that I've seen before include "award for work in theatre" , "Weller senior's nomination" , "Boy" , "Shortened man's name" , "award in America" .)
