Exaggerate somewhat, in more ways than one (4-3)

'exaggerate somewhat' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'more ways than one' is the wordplay.
I cannot quite see how this works, but
'more' could be 'over' (I've seen this before) and 'over' is present in the answer.
The remaining letters 'egg' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'in' is the link.

Can you help me to learn more?
