Modern variation of Wyatt, meaning brave in war
Rhyatt is a contemporary American invention, likely created by blending the traditional name Wyatt with the popular 'Rh-' prefix found in names like Rhys or Rhett. It retains the etymological roots of Wyatt, which derives from the Medieval English name Wyot, itself a diminutive of the Old English Wigheard.
