Wait and you'll get a bit of help in time (5)
I believe the answer is:
delay
'wait' is the definition.
(synonyms)
'help in time' is the wordplay.
'help' becomes 'el' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'time' becomes 'day' (day is a kind of time).
'el' inserted inside 'day' is 'DELAY'.
'and you'll get a bit of' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for delay that I've seen before include "Hold back" , "Stoppage" , "Defer; make late" , "Procrastinate - put off" , "Put off until later" .)
