Humorous, it comes to screen – the full-length version? (9,6)
I believe the answer is:
situation comedy
'version?' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for situation comedy that I've seen before include "Spoof" , "Friends in this" , "TV series noted for its humour" , "Bottom perhaps" , "TV programme" .)
