Where there’s no job for a dude (5)
I believe the answer is:
Here is my best explanation:
'where there's no job' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'a dude' is the wordplay.
I cannot quite see how this works, but
'a' could be 'an' and 'an' is located in the answer.
This may be the basis of clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
