Is removing its froth such a blow? (6)
I believe the answer is:
bitter
'blow?' is the definition.
The answer and definition can be both to do with perception as well as being verbs in their base form.
Maybe you can see a link between them that I can't see?
'is removing its froth such a' is the wordplay.
I cannot really understand how this works, but
'its' could be 'it' (I've seen this in other clues) and 'it' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bitter that I've seen before include "Beer; not sweet" , "Type of beer" , "Acerbic" , "English beer, sounds sour" , "Causing unhappiness" .)
