Asturian antes, Portuguese antes, Galician antes
Lapurdian aintzin "front," Roncalese antzin 'id.,' Zuberoan aitzin 'id.,' borrowed from a dialect in Proto-Romance
Anzes appears in both the Glosas Emilianenses (11th cent.) and the Glosas Silenses (11th cent.) as a gloss for Latin prius "before." This variant in either Old Spanish or Old Aragonese was probably close to what was borrowed by Basque. See Trask (2008).
