Nuclear families, which typically consist of parents and their children, are a common type of family structure. However, there are various terms that can be used to refer to this type of family. For instance, one could use the phrase "immediate family" to describe the same concept, as it refers to a group of individuals who are closely related by blood or marriage. Alternatively, the word "conjugal" can be used to refer to the relationship between a married couple and their offspring. Another term that can be used synonymously with nuclear families is "traditional family," which implies a family structure that adheres to cultural norms.
