I try ale brewed with such quality (7)
I believe the answer is:
reality
'such quality' is the definition.
The answer and definition can be both related to thinking as well as being singular nouns.
Maybe there's an association between them I don't understand?
'i try ale brewed' is the wordplay.
'brewed' is an anagram indicator.
'i'+'try'+'ale'='itryale'
'itryale' anagrammed gives 'REALITY'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for reality that I've seen before include "The world as it is" , "State of things as they actually exist" , "Actual existence" , "Type of television" , "The way things are, no illusions" .)
