Blubber about student accommodation (4)
I believe the answer is:
flat
'accommodation' is the definition.
(thesaurus)
'blubber about student' is the wordplay.
'blubber' becomes 'fat' ('fat' can be similar in meaning to 'blubber'**).
'about' indicates putting letters inside.
'student' becomes 'l' (as in L-plates for learner drivers).
'fat' going around 'l' is 'FLAT'.
(Other definitions for flat that I've seen before include "In music, below the correct pitch" , "Accommodation < still" , "Lacking interest" , "12 [TWO DIMENSIONAL]" , "Dull; apartment" .)
