Inherited from Old Spanish Yago, from Latin Iācōbus (“James”), from Ancient Greek Ἰάκωβος (Iákōbos), from Hebrew יַעֲקֹב (ya‘ăqṓḇ, “Jacob”, literally “he will/shall heel”), from עָקֵב (‘āqḗḇ, “heel”) and the Biblical account of the patriarch Jacob's birth in Genesis 25:26. Doublet of Jacobo and Jaime.
