Jacob

Uncertain; traditionally “heel-holder”, possibly “may God protect”

Jacob is a boys’ name of Hebrew origin, inherited through Greek and Latin forms. In Genesis, Jacob is born holding his twin Esau’s heel, giving the name its traditional “heel-holder” explanation. The story also plays on the idea of supplanting his brother. These are narrative wordplays; an older form meaning “may God protect” is another proposed origin. No single meaning is certain. That biblical background gives Jacob a classic feel, while its English sound can seem easygoing and warm. Pronounced /ˈdʒeɪkəb/, it puts the emphasis on the broad first syllable before settling into a quieter ending. The English short form Jake feels brisker and more informal.

Etymology: From Hebrew Yaʿaqov through Greek and Latin. The Bible links it to “heel”; an older meaning “may God protect” is also proposed.
