Film has an entertaining story (5)
I believe the answer is:
alien
'film' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'an entertaining story' is the wordplay.
'entertaining' is an insertion indicator.
'story' becomes 'lie' (story can mean a fabrication).
'an' going around 'lie' is 'ALIEN'.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for alien that I've seen before include "Foreign (from outer space?)" , "Martian, say" , "Creature from another planet" , "coming from overseas" , "Foreign - film directed by Ridley Scott" .)
