I believe the answer is:

forded

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

'got over' is the definition.
(fording is a kind of getting over)

I cannot understand how the remainder of the clue works.

(Other definitions for forded that I've seen before include "Crossed river at shallow point" , "Crossed river on foot at shallow place" .)

I've seen this clue in the Evening Standard.
