Get involved with Italian side show (8)
I believe the answer is:
interact
'get' is the definition.
(I know that get is a more specific form of give)
'with italian side show' is the wordplay.
'with' means one lot of letters go next to another.
'italian side' becomes 'inter' (Inter Milan football team).
'show' becomes 'act' (act can mean a show or facade).
'inter' next to 'act' is 'INTERACT'.
'involved' acts as a link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for interact that I've seen before include "Combine" , "Show effect on each other" , "Have a mutual effect" , "Work closely together" , "Affect one another mutually" .)
