>Basque l- can be originated in a former d-, as in Romance loanwords such as danger > lanjer (L, LN, Z) or disciplina > lizifrina (LN), liziprina (LN). But the coronal can in turn be derived from a labial, as in pesebre > lizifru (G), trisipu (G). This kind of delabialization also happened in older words such as betagin 'canine tooth' > letagin or pezoi(n) 'ditch, trench' > lezoi(n), the latter a Celtic loanword from *bedo-.
> As I said elsewhere, I regard
> pegor as a cognate of leihor, legor which retained the initial labial.
