Continent mining half of gold region (4,5)
I believe the answer is:
asia minor
'region' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe there's an association between them I don't understand?
'continent mining half of gold' is the wordplay.
'continent' becomes 'asia' (Asia is an example).
'half of' indicates taking half.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'mining' cut in half is 'min'.
'asia'+'min'+'or'='ASIA MINOR'
Can you help me to learn more?
(Other definitions for asia minor that I've seen before include "Historical land" , "Alternative name for Anatolia" , "several?" , "was visited by early missionary" , "part of Turkey" .)
