Such things happen even on the way back (6)
I believe the answer is:
events
'such things happen' is the definition.
I can't tell whether this defines the answer.
'even on the way back' is the wordplay.
'on' says to put letters next to each other.
'the way back' becomes 'ts' ('st' abbreviation for street, written backwards).
'even'+'ts'='EVENTS'
Can you help me to learn more?
(Other definitions for events that I've seen before include "Incidents, occurrences" , "Things taking place" , "Occurrences, happenings" , "Incidents, occasions" , "Important happenings or incidents" .)
