Chase Australian into usual place (5)
I believe the answer is:
haunt
'usual place' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'chase australian into' is the wordplay.
'chase' becomes 'hunt' (hunting is a kind of chasing).
'australian' becomes 'A' (common abbreviation).
'into' is an insertion indicator.
'hunt' enclosing 'a' is 'HAUNT'.
Can you help me to learn more?
(Other definitions for haunt that I've seen before include "A frequently visited place" , "Visit in spectral form" , "Keep appearing" , "Place regularly frequented" , "Frequent (a place)" .)
