A modified form of Ἰακώβ (Iakṓb), from Hebrew יַעֲקֹב (ya‘ăqṓḇ, “Jacob”, literally “heel-grabber”), from עָקֵב (‘āqḗḇ, “heel of the foot”). While Ἰακώβ (Iakṓb) refers to Jacob and Ἰάκωβος (Iákōbos) to James in the Greek writings, both English names derive from Ἰάκωβος (Iákōbos), which is derived from Ἰακώβ (Iakṓb).
