'Daddy' with a machine to run (5,3)
I believe the answer is:
crane fly
'run' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'daddy with a machine' is the wordplay.
'daddy' becomes 'fly' (I can't explain this - if you can you should believe this answer much more).
'with' is a charade indicator (letters next to each other).
'a machine' becomes 'crane'.
'fly' put after 'crane' is 'CRANE-FLY'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for crane fly that I've seen before include "A formal daddy-long-legs" , "One with long legs" , "Creature" , "Insect" .)
