Reiss

Reiss is a masculine name with Germanic and Welsh origins, functioning as both a surname and given name. As a German surname, it derives from 'Reis' meaning 'branch' or 'twig,' possibly indicating someone who lived near a brushwood thicket. In Welsh contexts, it relates to Rhys, meaning 'enthusiasm' or 'ardor.' As a first name, Reiss emerged relatively recently, gaining modest popularity in the UK and Australia since the 1990s. The double 's' spelling gives it a contemporary edge compared to alternative forms like Reese or Rhys. Compact yet distinctive, Reiss offers a modern sound while maintaining connection to traditional naming elements. Its cross-cultural appeal and strong, simple phonetics have contributed to its growing usage as a given name.

Reiss is also given to girls.
