Thrills with old quotes (7)
I believe the answer is:
excites
'thrills' is the definition.
(I've seen this before)
'with old quotes' is the wordplay.
'with' says to put letters next to each other.
'old' becomes 'ex' (prefix meaning former or onetime).
'quotes' becomes 'cites' ('cite' can be a synonym of 'quote').
'ex'+'cites' is 'EXCITES'.
(Other definitions for excites that I've seen before include "Makes eager" , "Stirs up, stimulates" , "Animates" , "Provokes" , "Thrills" .)
