Other forms: betrothals
A betrothal is a formal promise to marry. Announce the betrothal, break off the betrothal, a betrothal ceremony.
It was once a binding contract that could be sued on, which is why breaking one had consequences beyond the personal. The word is now archaic in English, and engagement has taken its place entirely.
