dolmen

dolmen: [19] English acquired the word dolmen for a ‘prehistoric structure of two upright stones surmounted by a horizontal one’ from French, but its ultimate source is Celtic. The element men means ‘stone’ (it occurs also in menhir [19], literally ‘long stone’) but there is disagreement about the first syllable. It is usually said to represent tōl ‘table’, a Breton borrowing from Latin tabula ‘board, plank’, but another view is that it is Cornish tol ‘hole’, and that the compound as a whole means literally ‘stone hole’, a reference to the aperture formed by the top stone lying on the two side stones.

dolmen (n.)

1859, from French dolmin applied 1796 by French general and antiquarian Théophile Malo Corret de La Tour d'Auvergne (1743-1800), perhaps from Cornish tolmen "enormous stone slab set up on supporting points," such that a man may walk under it, literally "hole of stone," from Celtic men "stone."

Some suggest the first element may be Breton taol "table," a loan-word from Latin tabula "board, plank," but the Breton form of this compound would be taolvean. "There is reason to think that this [tolmen] is the word inexactly reproduced by Latour d'Auvergne as dolmin, and misapplied by him and succeeding French archaeologists to the cromlech" [OED]. See cromlech, which is properly an upright flat stone, often arranged as one of a circle.
