Arouse reader (6)
I believe the answer is:
kindle
I believe this is a double definition.
'arouse' is the first definition.
(I know that arouse is a more specific form of excite)
'reader' is the second definition.
(the Kindle is an electronic reader)
(Other definitions for kindle that I've seen before include "reading facilitated by this?" , "Light (flame), arouse" , "Set alight" , "Light (fire)" , "Exclamation, shout" .)
