For the Dweomer magic of Katharine Kerr's Deverry books, see Dweomer (Deverry Cycle).

Dweomer, is the Old English word meaning 'witchcraft' that derives from the Old Norse term dvergmál literally meaning 'dwarf talk' (dvergr dwarf + mál talk), referring to the secret knowledge of magic among the Norse dwarves[citation needed]. See for instance the entry, dweomercræft. A related Middle English word that derives from the phrase 'dwarf talk', dwergma, means 'echo', crediting the dwarves who live in the stones with the sound[citation needed].

In role-playing games, like Dungeons & Dragons, and in fantasy novels, a dweomer is the magical aura on an enchanted item. More broadly, it may refer to the aura of a spell having been cast whose duration remains active[citation needed].
