Ximeno

Semen /ʂemen/ or Xemen /ʃemen/ is a medieval Basque given name of the Vasconic area. It is based on the Basque root seme < senbe 'son' as found in the ancient Aquitanian name Sembetten, attested form "sehi" as 'child', hypothetical ancient root *seni (cf. Koldo Mitxelena and modern form "senide" = 'brother or sister', 'relative'). The explanation by the Biblical name Šim’ōn (Simon) is less convincing.
