Runs over and falls (6)
I believe the answer is:
spills
This clue might be a double definition.
'runs over' is the first definition.
'spills' can be an answer for 'runs' (spilling is a kind of running). I am unsure of the 'over' bit.
'falls' is the second definition.
(spilling is a kind of falling)
'and' acts as a link.
Can you help me to learn more?
(Other definitions for spills that I've seen before include "Pieces of rolled paper used to light a fire" , "Pieces of rolled paper used to light fires" , "Causes liquid to flow out" .)
