Student is given time to register (4)
I believe the answer is:
list
'register' is the definition.
(listing is a kind of registering)
'student is given time' is the wordplay.
'student' becomes 'l'.
'is given' says to put letters next to each other.
'time' becomes 'ist' (I can't justify this - if you can you should give a lot more credence to this answer).
'l'+'ist'='LIST'
'to' is the link.
Can you help me to learn more?
(Other definitions for list that I've seen before include "as military recruits did once" , "choose" , "Leaning of a ship" , "Catalogue, roll" , "pay heed no longer" .)
