Proto-Basque: *hols (*holc)
Meaning: 1 plank 2 wall (made of planks) 3 cupboard, sideboard, dresser
Bizkaian: oltzar 1
Gipuzkoan: (arc) olz 2
High Navarrese: (arc) olz 2
Low Navarrese: oltz 2
Salazarese: oltza 2

Comments: Azkue cites oltza 'stack of planks' as common Bsq. As noted by Michelena (1961, chapter 14) the phonemic contrast between Proto-Bsq *ls and *lc is neutralized, but differently in different dialects. German Holz is a chance resemblance.
