Nature could be somewhere to find refreshment (3,3)
I believe the answer is:
tea urn
'somewhere to find refreshment' is the definition.
I can't tell whether this definition defines the answer.
'nature could be' is the wordplay.
'could be' is an anagram indicator.
'nature' is an anagram of 'TEA-URN'.
Can you help me to learn more?
(Other definitions for tea urn that I've seen before include "Container for brewing up in quantity" , "samovar" , "Water boiler" , "item in canteen" , "Nature (anag)" .)
