Kipling's poem about large sea captured on celluloid (6)
I believe the answer is:
filmed
'captured on celluloid' is the definition.
The answer and definition can be both to do with creating things as well as being past participle verbs.
Perhaps there's a link between them I don't understand?
'kipling's poem about large sea' is the wordplay.
'kipling's poem' becomes 'if' (I am not sure about this - if you are sure you should believe this answer much more).
'about' shows that the letters should be reversed in order.
'large' becomes 'L' (eg in clothes sizes).
'sea' becomes 'med' (abbreviation of Mediterranean).
'if' reversed gives 'fi'.
'fi'+'l'+'med'='FILMED'
Can you help me to learn more?
(Other definitions for filmed that I've seen before include "Made a movie" , "Shot" , "Made for cinema" .)
