There are no vines in Nashville synonymous, for instance, with the chateau's entry level (4)
I believe the answer is:
hall
'there are no vines in nashville synonymous for instance' is the definition.
I can't tell whether this defines the answer.
'with the chateau's entry level' is the wordplay.
'with' says to put letters next to each other.
'the chateau's' becomes 'hal' (I can't explain this - if you can you should give a lot more credence to this answer).
'entry' indicates taking the first letters (I've seen 'entry of' mean this).
The initial letter of 'level' is 'l'.
'hal' put next to 'l' is 'HALL'.
Can you help me to learn more?
(Other definitions for hall that I've seen before include "See 1" , "Large house (linked to Dotheboys, Wildfell and Toad)" , "College dining room" , "Large meeting room" , "Chamber" .)
