Stuff in college record (4)
I believe the answer is:
clog
'stuff' is the definition.
(thesaurus)
'college record' is the wordplay.
'college' becomes 'c'.
'record' becomes 'log' (logging is a kind of recording).
'c'+'log'='CLOG'
'in' acts as a link.
(Other definitions for clog that I've seen before include "Shoe with a thick wooden sole" , "Wooden footwear" , "Wooden shoe; choke up" , "Block with wooden-soled shoe?" , "Block; sabot" .)
