Conscious of Austrian goods, endlessly (5)
I believe the answer is:
aware
'conscious' is the definition.
(similar in meaning)
'of austrian goods endlessly' is the wordplay.
'of austrian' becomes 'awa' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'goods' becomes 'grey' (grey is a kind of goods).
'endlessly' indicates the central letters (the ends of the words are removed).
The middle letters of 'grey' are 're'.
'awa'+'re'='AWARE'
Can you help me to learn more?
(Other definitions for aware that I've seen before include "Acquainted with or mindful of" , "Acquainted with or conscious of" , "Bearing in mind" , "Conscious or having knowledge of" , "Attentive" .)
