Alternative to PC American upper-class casino resort? (5)
I believe the answer is:
macau
'casino resort?' is the definition.
The definition suggests a singular noun which matches the answer. I also know that 'casino' relates to this answer.
'alternative to pc american upper-class' is the wordplay.
I cannot really understand how this works, but
'pc' could be 'mac' (I've seen this before) and 'mac' is located in the answer.
'american' could be 'a' (common abbreviation - e.g. in organisation names) and 'a' is found within the answer.
'upper-class' could be 'u' (similar in meaning) and 'u' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for macau that I've seen before include "SW of 24 [SHANGHAI]" , "Part of China" , "region of China" , "somewhere in China" , "Small peninsula in China, a Portuguese territory until 1999" .)
