Comic jump on sleigh ending in catastrophe (3,4)
I believe the answer is:
bob hope
'comic' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'jump on sleigh ending in catastrophe' is the wordplay.
'jump' becomes 'hop' (hopping is a kind of jumping).
'on' means one lot of letters go next to another.
'sleigh' becomes 'bob'.
'ending in' indicates one should take the final letters.
The final letter of 'catastrophe' is 'e'.
'hop' put after 'bob' is 'bobhop'.
'bobhop'+'e'='BOB HOPE'
Can you help me to learn more?
(Another definition for bob hope that I've seen is " place of 1 8 [FLYING START]".)
