The word cairn derives from Scots (with the same meaning), in turn from Scottish Gaelic , which is essentially the same as the corresponding words in other native Celtic languages of Britain, Ireland and Brittany, including Welsh (and ), Breton , Irish , and Cornish or . Cornwall () itself may actually be named after the cairns that dot its landscape, such as Cornwall's highest point, Brown Willy Summit Cairn, a 5 m (16 ft) high and 24 m (79 ft) diameter mound atop Brown Willy hill in Bodmin Moor, an area with many ancient cairns. Burial cairns and other megaliths are the subject of a variety of legends and folklore throughout Britain and Ireland. In Scotland, it is traditional to carry a stone up from the bottom of a hill to place on a cairn at its top. In such a fashion, cairns would grow ever larger. An old Scottish Gaelic blessing is , I'll put a stone on your stone. In Highland folklore it is recounted that before Highland clans fought in a battle, each man would place a stone in a pile. Those who survived the battle returned and removed a stone from the pile. The stones that remained were built into a cairn to honour the dead. Cairns in the region were also put to vital practical use. For example, Dún Aonghasa, an all-stone Iron Age Irish hill fort on Inishmore in the Aran Islands, is still surrounded by small cairns and strategically placed jutting rocks, used collectively as an alternative to defensive earthworks because of the karst landscape's lack of soil.
