A quarter cent rise (6)
I believe the answer is:
ascent
'rise' is the definition.
(I know that rise can be written as ascent)
'a quarter cent' is the wordplay.
'quarter' becomes 's'.
'a'+'s'+'cent'='ASCENT'
(Other definitions for ascent that I've seen before include "Hill" , "Uphill journey" , "advancement" , "A rise in status; climb" , "Upward movement" .)
