On an outing do they come to grief? (8)
I believe the answer is:
trippers
'come to grief?' is the definition.
I can't judge whether this definition defines the answer.
'on an outing do they' is the wordplay.
'on' means one lot of letters go next to another.
'an outing' becomes 'trip' (I've seen this in another clue).
'do they' becomes 'pers' (I can't explain this - if you can you should believe this answer much more).
'trip' put next to 'pers' is 'TRIPPERS'.
Can you help me to learn more?
(Another definition for trippers that I've seen is " Tourists visiting sights of interest".)
