Speaks about a store (6)
I believe the answer is:
orates
'speaks' is the definition.
(orating is a kind of speaking)
'about a store' is the wordplay.
'about' is an anagram indicator.
'a'+'store'='astore'
'astore' with letters rearranged gives 'ORATES'.
(Other definitions for orates that I've seen before include "Talks pompously" , "Speaks formally, makes speech" , "Speechifies" , "Makes lengthy or pompous speech" , "Talks grandly from a platform" .)
