Humorous writing about following it and it returning (6)
I believe the answer is:
satire
'humorous writing' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'following it and it returning' is the wordplay.
'following' means one lot of letters go next to another.
'it' becomes 'sa' (old-fashioned abbreviation for sex appeal).
'and' is a charade indicator (letters next to each other).
'it' becomes ''t' (abbreviation. e.g. in 'tis).
'returning' becomes 'ire' (I can't explain this - if you can you should give a lot more credence to this answer).
'sa'+'t'='sat'
'sat'+'ire' is 'SATIRE'.
'about' is the link.
Can you help me to learn more?
(Other definitions for satire that I've seen before include "work with cutting devices?" , "Irony or sarcasm in speech or writing" , "sort of ironic humour" , "Caustic comments" , "Work of ridicule" .)
