Bonjour,
M'occupant de mettre en ligne en la rafraississant la page de
Concavata / Drumburg, en Cumberland, je trouve une indication sur une racine
*drum, que les auteurs renvoient à l'anglais ridge, pour lequel il est proposé, en français : dos, échine, crête, billon, faîte.
On doit donc y voir une notion de hauteur.
