Collection of people having no right to enter university (2,2)
I believe the answer is:
go up
'collection of people' is the definition.
The answer and definition can be both related to change as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'no right to enter university' is the wordplay.
I cannot quite understand how this works, but
'no' could be 'o' (O resembles 0) and 'o' is found within the answer.
'university' could be 'u' (abbreviation for university) and 'u' is present in the answer.
The remaining letters 'gp' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'having' is the link.
Can you help me to learn more?
(Other definitions for go up that I've seen before include "Rise" , "get promoted" .)
