Discount ring sent back twice (4-4)
I believe the answer is:
pooh-pooh
'discount' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Perhaps you can see a link between them that I can't see?
'ring sent back twice' is the wordplay.
'ring' becomes 'hoop' (synonyms).
'sent back' shows that the letters should be reversed in order.
'twice' shows that letters should be duplicated.
'hoop' back-to-front is 'pooh'.
'pooh' doubled is 'POOH-POOH'.
Can you help me to learn more?
(Other definitions for pooh-pooh that I've seen before include "Dismiss with contempt" , "Make dismissive sounds, ridicule repetitively?" , "Dismiss (something) rather contemptuously" , "Slight" , "Mock, make light of" .)
