A neonate is a newborn baby. New parents are usually excited and a little nervous to bring their neonate home from the hospital.

Use the noun neonate when you need a medical term for a tiny baby, specifically one that's younger than a month old. Hospitals have neonate units and neonate nurses, and what a doctor might refer to as a neonate, you'd probably just call an infant or a baby. Neonate combines the Greek prefix neo, or "new," and the Latin natus, "born."
