Singer Adkins accepts help in the capital (8)
I believe the answer is:
adelaide
'capital' is the definition.
(Adelaide is an example)
'singer adkins accepts help' is the wordplay.
I cannot really see how this works, but
'help' could be 'aide' (aide is a kind of help) and 'aide' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'in the' acts as a link.
Can you help me to learn more?
(Other definitions for adelaide that I've seen before include "19th century queen" , "where there was recently a test" , "Queen < in opera" , "Woman" , "South Australia's capital" .)
