I'm reading Jane Austen's Pride and Prejudice. At the end of chapter 29, she writes "The party then gathered round the fire to hear Lady Catherine determine what weather they were to have on the morrow."
At first I assumed it meant that the Lady Catherine De Bourgh would be so certain of what she expected the weather that it was as though she decided it rather than predicted. Then I started wondering if meaning of determine has shifted over the years, and it had simply meant predicted at the time.
In the early 19th century when Austen was writing, was the meaning of "determine" the same as it is today?
