Posh chap quaffed beer when talking about estate persistently (2,4,3,4,4)
I believe the answer is:
up hill and down dale
'estate persistently' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'posh chap quaffed beer when talking about' is the wordplay.
I cannot quite see how this works, but
'posh' could be 'u' (abbreviation for upper-class - opposite to non-U) and 'u' is found in the answer.
'chap' could be 'phil' and 'phil' is located in the answer.
'beer' could be 'ale' (type of beer) and 'ale' is located in the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for up hill and down dale that I've seen before include "all over the place" , "High and low" .)
