"ugly dwarf or giant," 1616, from O.N.
troll "giant, fiend, demon." Some speculate that it originally meant "creature that walks clumsily," and derives from P.Gmc.
*truzlan, from
*truzlanan (see
troll (v.)). But it seems to have been a general supernatural word, cf. Swed.
trolla "to charm, bewitch;" O.N.
trolldomr "witchcraft." The old sagas tell of the
troll-bull, a supernatural being in the form of a bull, as well as
boar-trolls. There were
troll-maidens, troll-wives, and
troll-women; the
trollman, a magician or wizard, and the
troll-drum, used in Lappish magic rites. The word was popularized in Eng. by 19c. antiquarians, but it has been current in the Shetlands and Orkneys since Viking times. The first record of it is from a court document from the Shetlands, regarding a certain Catherine, who, among other things, was accused of "airt and pairt of witchcraft and sorcerie, in hanting and seeing the Trollis ryse out of the kyrk yeard of Hildiswick." Originally conceived as a race of giants, they have suffered the same fate as the Celtic
Danann and are now regarded in Denmark and Sweden as dwarfs and imps supposed to live in caves or under the ground.
