Aroused old lover gets named (7)
I believe the answer is:
excited
'aroused' is the definition.
(exciting is a kind of arousing)
'old lover gets named' is the wordplay.
'old lover' becomes 'ex' (I've seen this in other clues).
'gets' means one lot of letters go next to another.
'named' becomes 'cited' ('cite' can be a synonym of 'name').
'ex'+'cited'='EXCITED'
(Other definitions for excited that I've seen before include "Animated" , "With feelings roused, emotionally high" , "Roused by strong emotion" , "Feeling a pleasant tension" , "Very eager and enthusiastic" .)
