Short description of Life of Brian : it's tremendous, for starters (4)
I believe the answer is:
obit
'short description of life' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'of brian it's tremendous for starters' is the wordplay.
'for starters' suggests taking the first letters.
The initial letters of 'of brian its tremendous' is 'OBIT'.
Can you help me to learn more?
(Other definitions for obit that I've seen before include "appreciation in media?" , "The last word" , "Biography after death, in short" , "provides announcement of death" , "Biographical death notice (abbr)" .)
