Outline for development namely shown by woman on carnival site (8)
I believe the answer is:
scenario
'outline for development' is the definition.
'scenario' can be an answer for 'outline' (thesaurus). I am not sure about the 'for development' bit.
'namely shown by woman on carnival site' is the wordplay.
'namely' becomes 'sc' (I've seen this in other clues).
'shown by' means one lot of letters go next to another.
'woman' becomes 'ena' (feminine given name).
'on carnival site' becomes 'rio' (I can't explain this - if you can you should believe this answer much more).
'sc'+'ena'+'rio'='SCENARIO'
Can you help me to learn more?
(Other definitions for scenario that I've seen before include "Film plot outline" , "Written outline of a film, novel, or stage work" , "Envisaged situation" , "Outline or synopsis of a play" , "Suggested plan of action" .)
