Words on parting very much in need of a trim? (2,4)
I believe the answer is:
so long
'words on parting' 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?
'very much in need of a trim?' is the wordplay.
'very much' becomes 'so'.
'in need of a trim?' becomes 'long' (I can't justify this - if you can you should believe this answer much more).
'so'+'long'='SO LONG'
Can you help me to learn more?
(Other definitions for so long that I've seen before include "Goodbye (colloq.)" , "Ta-Ta!" , "That length - goodbye!" , "Adieu" , "This extended" .)
