The Vietnamese word "đính hôn" is a verb that means "to promise to marry." It refers to the formal act of getting engaged, where two people agree to marry each other in the future. This is an important step in many cultures, including Vietnamese culture, as it signifies a commitment between partners.
While "đính hôn" primarily means "to promise to marry," it can sometimes be used in a broader sense to refer to the act of making a serious commitment in a relationship, not always leading directly to marriage.
