Limits spell in Italian capital (7)
I believe the answer is:
termini
'limits' is the definition.
(I've seen this before)
'spell in italian capital' is the wordplay.
'spell' becomes 'term' (term can mean a spell or period).
'capital' says to take the initial letters.
The initial letter of 'italian' is 'i'.
'term'+'in'+'i'='TERMINI'
(Other definitions for termini that I've seen before include "Final parts" , "Finishing points" , "Starting points, limits" , "Main railway stations" , "Some like Victoria" .)
