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

'the desire' is the definition.
(I've seen this in other clues)

'upset socially superior reg' is the wordplay.
I cannot quite understand how this works, but
'superior' could be 'u' (U can mean upper-class, as in U and non-U speech) and 'u' is located in the answer.
an anagram of 'reg' is 'rge' which is present in the answer.
No letters remain.
This explanation may well be incorrect...

'to' is the link.
