eva

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

'lady's' is the definition.

'greeting reflected' is the wordplay.
'greeting' becomes 'ave' (Latin greeting).
'reflected' is a reversal indicator (letters reflected back).
'ave' reversed gives 'EVA'.

'formal' is the link.
This may not be right. It may belong to another bit of the clue.

Can you help me to learn more?
