A family with a large number of children can be described as philoprogenitive, as can an animal that births litters and a plant that takes over the garden. The adjective comes from the Latin verb “progignere,” meaning “to beget” (“to father, or produce as offspring”). The prefix “phil-” means “loving,” which explains the secondary meaning of the word, “relating to love of offspring.” A parent with only one child can still be philoprogenitive by having great love for their child.
