perineum

• perinaeum, perinæum

Borrowed from Late Latin perinaeum, from Ancient Greek περίναιον (perínaion, “space between the anus and scrotum”), from Ancient Greek περίνεος, περίνεοι (períneos, períneoi, “male genitals”), itself from earlier Ancient Greek περίς (perís, “penis”) through influence from Ancient Greek πηρίς (pērís, “scrotum”).
