This formal term has a related modern slang term: “nepo baby.” Hollywood is rife with the so-called “nepotism babies,” or those who have gained notoriety, jobs, and wealth based on their propinquity to celebrity parents. “Propinquity” comes from the Latin term “propinquus,” meaning “near,” but it entered Old French as “propinquité” before appearing in Middle English. The noun can refer to a literal kinship, or it can refer to a state of being close to someone or something in proximity.
