Film studio ultimately competes in cinema (6)
I believe the answer is:
movies
'film studio ultimately competes in cinema' is the definition.
I can't tell whether this defines the answer.
'film studio ultimately competes' is the wordplay.
'ultimately' indicates one should take the final letters.
'competes' becomes 'vies' ('vie' can be a synonym of 'compete').
The last letters of 'film studio' are 'mo'.
'mo'+'vies'='MOVIES'
Can you help me to learn more?
(Other definitions for movies that I've seen before include "big-budget features" , "Informally, films shown in cinemas" , "Flicks" , "Films in America" , "Motion pictures" .)
