It's good for Ali to be in love and show animation (4,5)
I believe the answer is:
look alive
'show animation' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'it's good for ali to be in love' is the wordplay.
'it's good' becomes 'ok'.
'for' is a charade indicator (letters next to each other).
'to be in' means one lot of letters goes inside another.
'ok'+'ali'='okali'
'okali' placed inside 'love' is 'LOOK ALIVE'.
'and' acts as a link.
Can you help me to learn more?
(Another definition for look alive that I've seen is " Come on".)
