Ramble finished back to front (4)

I believe the answer is:

rove

I'm a little stuck... Click here to teach me more about this clue!

'ramble' is the definition.
(I know that ramble can be written as rove)

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for rove that I've seen before include "Roam about aimlessly" , "Wander or walk about" , "Wander aimlessly" , "Knock about" , "Range" .)
