Amorous, making old Italian twitch (8)
I believe the answer is:
'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).
'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" .)
