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

'impress greatly?' is the definition.
'bowl over' can be an answer for 'impress' (I've seen this before). I am not sure about the 'greatly?' bit.

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for bowl over that I've seen before include "Overwhelm with surprise - in cricker?" , "Knock down" , "Thoroughly delight" , "wow" , "Greatly surprise" .)

I've seen this clue in The Hindu.
