Pro-genitor refers to an ancestor or a biological parent. Its antonyms can be descendants, offspring, or posterity. Descendants are people who come after a particular ancestor or progenitor, while offspring implies genetic or maternal relations. Posterity refers to all future generations of people, and the term can be connected to a particular ancestor. The antonyms of progenitor may also include unrelated persons, such as adoptive parents, foster parents, or step-parents. In contrast to a progenitor who is biologically related, these individuals become parents through legal or social means. The vocabulary related to the concept of family and heritage can be versatile and complex, reflecting the diversity of relationships and life experiences.
