betroth

The word betroth means to promise someone in marriage—to formally pledge oneself to another with the intention of marrying them. It's an older, more formal term than "engage," carrying connotations of tradition, ceremony, and often societal or familial involvement. A betrothal is usually a solemn pre-wedding commitment, sometimes with legal and social consequences.

Historically, betrothals were significant legal and social contracts, particularly among nobility and royalty. They weren't simply about love; they were about alliances, inheritance, and the continuation of family lines. A betrothed couple might not marry immediately—the period between betrothal and marriage could be months or years—while the commitment was still considered binding.

Today, betroth is rarely used in everyday conversation. You're more likely to encounter it in literature, historical fiction, or fantasy stories where a sense of old-world romance and formality is desired. For example: "Prince Charming betrothed himself to Cinderella," or "The princess was betrothed to the neighboring king's son."

While you might become engaged, people are betrothed to each other—often through a formal act that places both parties under an explicit promise. It suggests a commitment that goes beyond simple affection and leans toward destiny, duty, and obligation. So, if you want to evoke a sense of old-world romance and a solemn vow, betroth is the word to use.
