As a finish to hatter's ambition? (2,3,2,3)
I believe the answer is:
to cap it all
'as a finish' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'to hatter's ambition?' is the wordplay.
I cannot quite see how this works, but
'to' is present in the answer.
The remaining letters 'capitall' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for to cap it all that I've seen before include "On top of everything else" , "To provide the finishing touch" , "Finally" , "As a (frequently unwanted) climax" , "as a last straw" .)
