Cry of student overwhelmed by stress (5)
I believe the answer is:
bleat
'cry' is the definition.
(bleat is a kind of cry)
'student overwhelmed by stress' is the wordplay.
'student' becomes 'l' (as in L-plates for learner drivers).
'overwhelmed by' is an insertion indicator (I've seen this in other clues).
'stress' becomes 'beat' (I can't justify this - if you can you should give a lot more credence to this answer).
'l' placed inside 'beat' is 'BLEAT'.
'of' is the link.
Can you help me to learn more?
(Other definitions for bleat that I've seen before include "Lamb's cry" , "Complain; sheep's cry" , "Sound made by goat" , "Sound from the fold" , "Make complaint" .)
