Mr Bingley had soon made himself acquainted with...
Contemporary phrasing would be more direct:
- Mr Bingley had soon acquainted himself with...
- Mr Bingley quickly introduced himself to
You can see how the self-referential 'had made himself' phrasing lets Austen come at the action more obliquely.
Can you rephrase a verb group to be more self-referential in this way?
Talked of giving one himself
We don't use 'of' this way much anymore. We'd use 'about':
- He talked about giving one himself
Can you find an opportunity for your character to speak, talk or know about something, but use 'of' instead of about?
Such amiable qualities
We don't use 'such' as a pointer much anymore. We'd say something like:
- These amiable qualities
- These types of amiable qualities
Is there a pointer you can switch for 'such'?
