A modern blend of Jan and Anthony
Janthony is a contemporary American portmanteau, likely created by combining the prefix Jan- with the classic name Anthony. While Jan can have roots meaning 'God is gracious,' and Anthony means 'priceless one,' this specific combination is a modern invention without a singular historical etymology.
Fewer than 5 boys were named Janthony in 2025.
