Complaint from student in club (5)
I believe the answer is:
bleat
'complaint' is the definition.
(I've seen this before)
'student in club' is the wordplay.
'student' becomes 'l' (as in L-plates for learner drivers).
'in' means one lot of letters goes inside another.
'club' becomes 'beat' (I've seen this before).
'l' inserted into 'beat' is 'BLEAT'.
'from' is the link.
(Other definitions for bleat that I've seen before include "Sound sheepish" , "Cry like a 16" , "Cry plaintively" , "Plaintive cry" , "Sound made by goat" .)
