I'm a little stuck... Click here to teach me more about this clue!

'exiled without husband after old' is the definition.
I can't judge whether this definition defines the answer.

'city became more industrial' is the wordplay.
I cannot quite see how this works, but
'city' could be 'urban' (urban means relating to a city) and 'urban' is found in the answer.
This explanation may well be incorrect...
