Live with students and young fellow hack in terrible dive (5-4)
I believe the answer is:
belly-flop
'dive' is the definition.
(I know that belly-flop is a type of dive)
'live with students and young fellow hack in terrible' is the wordplay.
I cannot quite understand how this works, but
'live' could be 'be' (synonyms) and 'be' is located in the answer.
'students' could be 'll' (two abbreviations for learner) and 'll' is found in the answer.
'young' could be 'y' and 'y' is located in the answer.
'fellow' could be 'f' (abbreviation - of a society etc.) and 'f' is located in the answer.
'hack' could be 'lop' (both can mean to cut up) and 'lop' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for belly-flop that I've seen before include "Awkward dive" , "Inexpert dive" .)
