Pray do not talk of that odious man. I do think it is the hardest thing in the world, that your estate should be entailed away from your own children; and I am sure if I had been you, I should have tried long ago to do something or other about it.

– Jane Austen

Pride and Prejudice, Chapter 13. Mrs. Bennet cannot bear to hear Mr. Bennet mention the name of Mr. Collins. Collins is a reminder to the exasperated mother of five daughters of their inability to produce a son and keep their estate within the family. For Longbourn being under an entail means that only a male heir can inherit the estate, so in the event of Mr. Bennet’s death it goes to his cousin Mr. Collins.
