Look for brochure American left (8)
I believe the answer is:
prospect
'look for' is the definition.
(thesaurus)
'brochure american left' is the wordplay.
'brochure' becomes 'prospectus' (I've seen this before).
'american' becomes 'us' (abbreviation for United States).
'left' is a deletion indicator.
'prospectus' with 'us' taken out is 'PROSPECT'.
(Other definitions for prospect that I've seen before include "Outlook or panorama" , "Possible customer" , "'Outlook, vista (8)'" , "Explore in search of something, perhaps gold" , "View - chances" .)
