Iapheth is Hebrew in Origin.

Iapheth is the Hellenized/Latinized spelling of the biblical name commonly rendered Japheth, borne by one of Noah’s sons. In the Septuagint it appears as Ἰάφεθ (Iapheth), reflecting a Hebrew form Yefet/Yephet (יֶפֶת). The name is traditionally linked to the Hebrew verb p-t-h “to enlarge/open,” yielding the sense “expansion,” “may he be enlarged,” echoed in Genesis 9:27. A secondary, folk etymology connects it to beauty (y-f-h), but this is less secure.

Long embedded in Jewish, Christian, and Islamic lore as progenitor of many nations - often Europe and parts of Asia - the name surfaced in medieval and early modern records but remains rare today. Variants include Japheth, Japhet, Jafet (Spanish/Portuguese), Yefet (Hebrew), Yāfith (Arabic), Iafeth/Iaphet (older English/Latin), and Turkish Yafes; related feminine Israeli Yafit is distinct. Historical bearers include the 10th–11th‑century Karaite scholar Yefet ben ‘Ali. Contemporary use is uncommon, suiting parents seeking an ancient, cross‑cultural choice.
