'be' is the definition.
Although both the answer and definition are verbs in their base form, I don't understand how one could define the other.

'good as and rise as high as' is the wordplay.
I cannot really see how this works, but
'rise' could be 'comeup' (synonyms) and 'comeup' is present in the answer.
The remaining letters 'to' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).

'as' is the link.
