Amorous, making old Italian twitch (8)
I believe the answer is:
romantic
'amorous' is the definition.
(I know that amorous can be written as romantic)
'old italian twitch' is the wordplay.
'old italian' becomes 'roman' (I've seen this before).
'twitch' becomes 'tic' (tic is a kind of twitch).
'roman'+'tic'='ROMANTIC'
'making' acts as a link.
(Other definitions for romantic that I've seen before include "Soulful or amourous idealist" , "Inclined to love" , "Soulful or amorous idealist" , "Visionary" , "Having an idealised view of reality" .)
