Marriageable age refers to the legal age at which a person is considered to be eligible for marriage. However, there are various synonyms that can be used to describe this age limit. Some common examples include nubile age, ripe age, eligible age, matrimonial age, unionable age, wedlock age, and spousal age. These terms are often used interchangeably to describe the age range at which individuals are considered suitable candidates for marriage and/or social expectations around when people should tie the knot. Ultimately, the specific age range considered as "marriageable" varies depending on cultural and legal norms, as well as individual preferences.
