Definition - to run away from one's husband with a lover
For many of us the word elope conjures up dramatic imagery of forbidden love and excitement, young lovers fleeing parental disapproval in order that they might marry. In this context the verb is often found paired with the preposition with. However, the word has another, related, sense, in which at least one party (in addition to parents) is not very happy. This is the sense in which a woman leaves her husband for her lover (and is typically paired with the preposition from).
Also for a man that liueth asunder from his wife, there lyeth Action in a Court Ecclesiastical, for him to receiue her againe and to cohabite with her; as may be gathered by that statute of Westminster the second; where it is prouided; that a woman eloped from her husband, shall loose her dower: except the husband (without compulsion Ecclesiasticall) doe receiue her againe.
