James.

The English New Testament form of Jacob, from Middle English James, from Old French James, from Vulgar Latin Iācōmus, spoken and altered pronunciation of Latin Iācōbus, from Ancient Greek Ἰάκωβος (Iákōbos), from Ἰακώβ (Iakṓb), from Biblical Hebrew יַעֲקֹב (yaʿăqōḇ, literally “May He Heel”), from the third-person singular masculine imperfective form of the Semitic verb "to heel" (with various meanings), in turn from עָקֵב (ʿāqēḇ, “heel of the foot”). Doublet of Jacques, Jacob, Iago, Jago, Yago, Hamish, Seamus, Tiago, Santiago, and Yaakov. In reference to the Ecuadorian island, a modification of the earlier name Duke of York's Island after its eponymous duke's coronation as James II of England. See Occitan Jacme for an intermediary between Old French James and Catalan Jaume.
