What it means
A modern short form of Jackson or Jaxon, ultimately 'son of Jack' (a pet form of John, 'God is gracious').
Jax is a punchy modern short for Jackson or Jaxon, tracing back through Jack to John, 'God is gracious.' The sharp -x ending puts it in the trendy company of Knox, Maddox, and Jett. Sons of Anarchy's Jax Teller gave it a rugged edge, and it climbed fast in the 2010s. Short, sharp, and built for the modern ear.
