Kindle's former name (6)
I believe the answer is:
excite
'kindle's' is the definition.
(exciting is a kind of kindling)
'former name' is the wordplay.
'former' becomes 'ex'.
'name' becomes 'cite' (I've seen this in other clues**).
'ex'+'cite'='EXCITE'
(Other definitions for excite that I've seen before include "Get worked up" , "Cause (someone) to feel very enthusiastic" , "Act as a stimulant" , "Stimulate - arouse" , "Kindle" .)
