Registers tips (5)
I believe the answer is:
lists
I believe this clue is a double definition.
'registers' is the first definition.
(listing is a kind of registering)
'tips' is the second definition.
(list can mean to tilt or tip over)
(Other definitions for lists that I've seen before include "where knights once fought" , "field of combat" , "Catalogues, rolls" , "where combat took place?" , "Silts up and leans over" .)
