I'm a little stuck... Click here to teach me more about this clue!

'i get it finally' is the definition.
I can't tell whether this defines the answer.

'university dons resend after mix-up' is the wordplay.
'university' becomes 'U' (abbreviation for university).
'dons' means one lot of letters goes inside another (don can mean to wear or be covered in).
'after mix-up' indicates an anagram.
'resend' with letters rearranged gives 'endser'.
'u' put into 'endser' is 'END-USER'.
