In geology, a boulder is a rock fragment with size greater than 256 millimetres (10.1 in) in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive.
In common usage, a boulder is too large for a person to move. Smaller boulders are usually just called rocks (American English) or stones (In British English a rock is larger than a boulder). The word boulder is short for boulder stone, from Middle English bulderston or Swedish bullersten.In places covered by ice sheets during Ice Ages, such as Scandinavia, northern North America, and Siberia, glacial erratics are common. Erratics are boulders picked up by ice sheets during their advance, and deposited when they melt.

Alba (English: ) is the Scottish Gaelic name (pronounced [ˈal̪ˠapə]) for Scotland. It is cognate with the Irish term Alba (gen. Alban, dat. Albain) and the Manx term Nalbin, the two other Goidelic Insular Celtic languages, as well as contemporary words used in Cornish (Alban) and Welsh (Yr Alban), both of which are Brythonic Insular Celtic languages.
