betroth (someone or oneself) to (someone)

1. To arrange a marriage between two people. Is it true that Lady Edith's family really betrothed her to that horrid man? My family has betrothed my sister to Alistair, and they are to be married in the spring. Yes, my parents want to betroth me to that woman, but I'm not too fond of her.

2. To agree or vow to marry someone. A: "Why would Alice betroth herself to someone so disreputable?" B: Well, he does have money." I would gladly betroth myself to a beauty like her! A: "I heard that mysterious visitor has betrothed himself to one of the ladies in town." B: "What? But he's only been here a few weeks!"
