erce

Etymology
Attested in the 11th-century Æcerbot ("field-remedy") charm. The triple invocation erce, erce, erce is compared to the Latin sanctus, sanctus, sanctus, and interpreted as derived from a vocative form of eorcnan "true, genuine; holy", or a proper name Erce, from an earlier *Eorce for a fertility goddess addressed as "mother of earth".
