New university students amounting to nothing (4)
I believe the answer is:
null
'amounting to nothing' is the definition.
(I've seen this before)
'new university students' is the wordplay.
'new' becomes 'n'.
'university' becomes 'u'.
'students' becomes 'll'.
'n'+'u'+'ll'='NULL'
(Other definitions for null that I've seen before include "Legally void" , "Non-existent and void" , "Having the value zero -- void" , "... and void, lacking any legal or binding force" , "Without force, validity" .)
