Precursor of a fall on an outing (4)
I believe the answer is:
trip
This clue could be a double definition.
'precursor of a fall' is the first definition.
'trip' can be an answer for 'fall' (as in tripping over). I am unsure of the 'precursor of a' bit.
'an outing' is the second definition.
(I've seen this before)
'on' acts as a link.
Can you help me to learn more?
(Other definitions for trip that I've seen before include "Jaunt" , "Pleasure excursion" , "A short journey - stumble on it" , "Set off for" , "Stumble - excursion" .)
