"Pinkman: Doire-na-heilte = Oakwood of the doe. Eilit, a hind, a doe and, figuratively, a tall ill-dressed woman. Doire is sometimes contracted to der in anglicized names. It is a very common word in the construction of place-names. About 1300 names begin with the word in one or other of its carious forms, and a very considerable number have it as a termination. If, as is likely, an oakwood once grew in those places, we have evidence of the great abundance of this tree in early times. The Brehon Code placed the ok among the ‘chieftain’ trees, and arranged a special fine for illegal interference with it. It was valued for its usefulness, for its noble size and appearance, and for its ‘meas’ or acorns. Its bark was much used in tanning. "
