Navarro-Labourdin or Navarro-Lapurdian is a Basque dialect spoken in the Lower Navarre and Labourd (Lapurdi) former provinces of the French Basque Country (in the Pyrénées Atlantiques département). It consists of two dialects in older classifications, Lower Navarrese and Labourdin. It differs somewhat from Upper Navarrese spoken in the Spanish Basque Country.
Lower Navarrese or Low Navarrese (Standard Basque: Nafarroa Beherea) is actually two subdialects, eastern and western; the western dialect continues into eastern Labourd. Labourdin (French Labourdin; Standard Basque Lapurtera, locally Lapurtara) is spoken in western Lapurdi.
Labourdin is felt by speakers of other dialect to be clear-cut and elegant, retaining like other French Basque dialects the consonant /h/, and it was used along with Gipuzkoan and High Navarrese in the creation of the Batua, a standardised form of Basque intended for teaching and the media.
Classic Labourdin was a literary language of the 17th century, used by authors such as Axular. The type of syllable stress in Hondarribian Basque is considered to be a remainder of the one that may have been used in Classic Lapurdian.
