Exceptionally large estate maybe getting award (5)
I believe the answer is:
oscar
'award' is the definition.
(Academy Award)
'exceptionally large estate maybe getting' is the wordplay.
'exceptionally large' becomes 'os' (abbreviation for oversize. I am not sure about the 'exceptionally' bit.).
'estate maybe' becomes 'car' (estate is a type of car).
'getting' says to put letters next to each other.
'os'+'car'='OSCAR'
Can you help me to learn more?
(Other definitions for oscar that I've seen before include "Librettist Hammerstein, d. 1960" , "to wit involved in row" , "Note" , "Statuette awarded by Hollywood Academy" , "One of several given to Chicago" .)
