'completely' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'heartily exhilarated students finish drink' is the wordplay.
'heartily' indicates the central letters.
'students' becomes 'll'.
'finish' becomes 'end' (synonyms).
'drink' becomes 'sup' (I've seen this before).
The middle letter of 'exhilarated' is 'a'.
'a'+'ll'+'end'+'sup'='ALL ENDS UP'
