Come on dreadfully empty intentionally funny film (6)
I believe the answer is:
comedy
'intentionally funny film' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'come on dreadfully empty' is the wordplay.
'on' says to put letters next to each other (in a down clue, letters appear on others).
'empty' means to remove the middle letters.
'dreadfully' with its centre removed is 'dy'.
'come'+'dy'='COMEDY'
Can you help me to learn more?
(Other definitions for comedy that I've seen before include "Light and humorous drama" , "Amusing drama" , "Dante's divine work" , "Play with happy ending" , "film like Doctor in the House" .)
