Wherein high living is apt to be cheap (5)
I believe the answer is:
attic
'wherein high' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
I also know that 'high' relates to this answer.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for attic that I've seen before include "Top chamber" , "where high-ups are found?" , "28 [GREEK]" , "Upstairs room" , "top-flight accommodation" .)
