(Other definitions for store that I've seen before include "Large shop; computer memory" , "Eg, granite" , "Reserve, shop" , "Put by; shop" , "Save" .)
(Other definitions for parlour that I've seen before include "where cows are milked!" , "Room in public house" , "Private sitting room" , "Lounge, reception room" , "Room for receiving guests in a monastery" .)
(Other definitions for malt that I've seen before include "Whisky ingredient" , "Kind of Scotch whisky" , "Brewing ingredient derived from grain" , "Ingredient of beer" , "Barley product used in brewing" .)
