india

I'm a little stuck... Click here to teach me more about this clue!

'huge country' is the definition.
'India' can be an answer for 'country' (India is an example). I'm unsure of the 'huge' bit.

'home help is coming round' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'help' becomes 'aid' (synonyms).
'is coming round' is a reversal indicator.
'aid' back-to-front is 'dia'.
'in'+'dia'='INDIA'

Can you help me to learn more?
