'mostly metal or otherwise covering tip of superconductor' is the definition.
I can't tell whether this definition defines the answer.

'mostly metal or otherwise covering tip of superconductor' is the wordplay.
'mostly' means to remove the last letter (most but not all of the word).
'otherwise' indicates anagramming the letters.
'covering' is an insertion indicator.
'tip of' says to take the initial letters.
The initial letter of 'superconductor' is 's'.
'metal' with its last letter removed is 'meta'.
'meta'+'or'='metaor'
'metaor' anagrammed gives 'maetro'.
'maetro' placed around 's' is 'MAESTRO'.
