Remove outer layer and reportedly, jump back (4)
I believe the answer is:
peel
'remove' is the definition.
(I know that peel is a more specific form of the action take off)
'outer layer and reportedly jump back' is the wordplay.
'outer layer' becomes 'l' (I can't justify this - if you can you should give a lot more credence to this answer).
'and' is a charade indicator (letters next to each other).
'reportedly' indicates a 'sounds like' (homophone) clue.
'back' suggests the final letters (the letter at the back).
The last letter of 'jump' is 'p'.
'p' is a homophone of 'pee'.
'l' put after 'pee' is 'PEEL'.
Can you help me to learn more?
(Other definitions for peel that I've seen before include "Citrus skin" , "Remove the rind" , "Remove skin from, say apple" , "Remove skin of vegetable or fruit" , "old tower" .)
