Covering up not criminal case? Having more to say (6)
I believe the answer is:
adding
'covering up not criminal case?' is the definition.
The definition and answer can be both to do with communicating as well as being present participle verbs.
Perhaps you can see a link between them that I can't see?
'more to say' is the wordplay.
'more' becomes 'ing' (I can't explain this - if you can you should believe this answer much more).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'say' becomes 'add' (adding is a kind of saying).
'ing' after 'add' is 'ADDING'.
'having' acts as a link.
Can you help me to learn more?
(Other definitions for adding that I've seen before include "increasing it by" , "Totalling" , "Totting" , "Appending" , "Putting in" .)
