'with' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'a plate he can certainly make the earth move' is the wordplay.
I cannot quite see how this works, but
'a' could be 'an' and 'an' is present in the answer.
'he' could be 'jude' and 'jude' is found within the leftover letters.
This may be the basis of clue (or it may be nonsense).
