The term "eloper" is generally used to refer to someone who runs away to get married without the knowledge or consent of his or her family members. However, there are many other synonyms that can be used to refer to such a person. For instance, the term "runaway bride or groom" is also widely used. Other synonyms that can be used to describe an eloper include "elopee," "runaway spouse," "fugitive bride/groom," "secret lover," "deserter," "rebel without a cause," or "non-conformist." Each of these synonyms highlights a slightly different aspect of eloping and can be used interchangeably to suit the context.
