A superpower strikes trouble drawing up here? (9)
I believe the answer is:
australia
'here?' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'a superpower strikes trouble drawing up' is the wordplay.
'superpower' becomes 'US' (the United States is a global superpower).
'strikes trouble' becomes 'ail' (I am not sure about this - if you are sure you should believe this answer much more).
'drawing' becomes 'art' (drawing is an art).
'up' is a reversal indicator (in down clue: letters go upwards).
'ail'+'art'='ailart'
'ailart' reversed gives 'tralia'.
'a'+'us'+'tralia'='AUSTRALIA'
Can you help me to learn more?
(Other definitions for australia that I've seen before include "Derby winner" , "Commonwealth country" , "USA lariat found down under" , "Test match players" , "Antipodean continent" .)
