Disgusted, refuse to carry any further (3,3)
I believe the answer is:
put off
'disgusted refuse' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Maybe you can see an association between them that I can't see?
'to carry any further' is the wordplay.
I cannot quite see how this works, but
'to' is present in the answer.
The remaining letters 'puff' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for put off that I've seen before include "Defer - deter" , "Don't ... ... till tomorrow what can be done today" , "Deter; deterred" , "Don't encourage - delay" , "Defer to a later time, or alienate" .)
