Jacobus is in Origin.

A Latinized form of Jacob/James, Jacobus derives from Latin Iacobus, itself from Hebrew Yaʿaqov, linked to ʿaqev “heel.” The name is usually interpreted as “holder of the heel” or “supplanter,” echoing the biblical Jacob who grasped his brother’s heel. In church Latin and scholastic records, Jacobus functioned as the formal register of both Saint James the Greater and the Lesser, and it remained a preferred learned style in Renaissance and Reformation Europe.

Enduring in the Low Countries and South Africa, Jacobus has long served as a Dutch and Afrikaans baptismal name, yielding nicknames and short forms such as Jacob, Jaap, Sjaak, Coos, Koos, and Kobus. Related forms include English Jacob and James, French Jacques, Italian Giacomo, Spanish Jacobo, Portuguese Jacó, and Scots/Irish Seumas/Seamus via the same lineage. Variant spellings Iacobus and Jakobus appear in Latin or Germanic contexts; patronymics like Jacobs and Jacobsen stem from it.
