University's new stewards becoming sloppy (2,7)
I believe the answer is:
st andrews
'university's' is the definition.
(I've seen this before)
'new stewards becoming sloppy' is the wordplay.
'new' becomes 'n' (abbreviation as in New Testament NT).
'becoming sloppy' is an anagram indicator.
'n'+'stewards'='nstewards'
'nstewards' with letters rearranged gives 'ST ANDREWS'.
(Other definitions for st andrews that I've seen before include "Famous golf course in Scotland, named after patron saint" , "sporting venue" , "town with notable links" , "University" , "links courses old and new" .)
