A variety of the language, Lucumi, is the liturgical language of the Santería religion of the Caribbean. Many Yoruba words are used in the Afro-Brazilian religion known as Candomblé. Yoruba is most closely related to the Itsekiri language (spoken in the Niger Delta) and to Igala (spoken in central Nigeria)., Obalokun was an Alaafin of Oyo , he was first in an era of successive despotic and short - lived kings of Oyo ., Yorubaland is the cultural region of the Yoruba people in West Africa. It spans the modern day countries of Nigeria, Togo and Benin, and covers a total land area of 142,114 km² or about the same size as the combined land areas of Greece and Montenegro, of which 106,016 km², representing about 74.6% within Nigeria, 18.9% in Benin, and the remaining 6.5% in Togo.

The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight., The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain, Scandinavia, Germany, the Netherlands, Belgium, and France.

Fit walkers can continue west for a circular walk around the loch taking in a Corbett , Sròn a ' Choire Chnapanich , and another Munro , Meall Buidhe ., The Scottish Mountaineering Club (SMC) is Scotland's second oldest mountaineering club. (the Cairngorm Club was founded a few months earlier.) Founded in 1889, in Glasgow, the private club, with about 400 members, publishes guidebooks and runs a list of Munroists., Great Britain, also known as Britain , is a large island in the north Atlantic Ocean off the northwest coast of continental Europe. With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61 million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of it, and together these islands, along with over 1,000 smaller surrounding islands, comprise the British Isles archipelago., The Hebrides (Scottish Gaelic: "Innse Gall"; Old Norse: "Suðreyjar") comprise a widespread and diverse archipelago off the west coast of mainland Scotland. There are two main groups: the Inner and Outer Hebrides. These islands have a long history of occupation dating back to the Mesolithic, and the culture of the residents has been affected by the successive influences of Celtic, Norse, and English-speaking peoples. This diversity is reflected in the names given to the islands, which are derived from the languages that have been spoken there in historic and perhaps prehistoric times., The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe.

Munros are named after Sir Hugh Munro, 4th Baronet (18561919), who produced the first list of such hills, known as "Munro's Tables", in 1891. A Munro top is a summit that is not regarded as a separate mountain and which is over 3,000 feet. In the 2012 revision of the tables, published by the Scottish Mountaineering Club, there are 282 Munros and 227 further subsidiary tops. Of these 200 have a topographic prominence of over and are regarded by Peakbaggers as Real Munros. There are 88 Metric Munros which are Scottish mountains over 1000m with a topographic prominence of over . The best known Munro is Ben Nevis, the highest mountain in the British Isles., The Irish Sea (, , , Ulster-Scots: "Airish Sea"), separates the islands of Ireland and Great Britain. It is connected to the Celtic Sea in the south by St George's Channel, and to the Inner Seas off the West Coast of Scotland in the north by the North Channel. Anglesey is the largest island within the Irish Sea, followed by the Isle of Man. The sea is occasionally, but rarely, referred to as the Manx Sea., The Northern Isles  is an archipelago comprising a chain of islands off the north coast of mainland Scotland. The climate is cool and temperate and much influenced by the surrounding seas. There are two main island groups: Shetland and Orkney. There are a total of 26 inhabited islands with landscapes of the fertile agricultural islands of Orkney contrasting with the more rugged Shetland islands to the north, where the economy is more dependent on fishing and the oil wealth of the surrounding seas. Both have a developing renewable energy industry. They also share a common Pictish and Norse history. Both island groups were absorbed into the Kingdom of Scotland in the 15th century and remained part of the country following the formation of the Kingdom of Great Britain in 1707, and later the United Kingdom after 1801. The islands played a significant naval role during the world wars of the 20th century., The British Isles are a group of islands off the north-western coast of continental Europe that consist of the islands of Great Britain, Ireland and over six thousand smaller isles. Situated in the North Atlantic, the islands have a total area of approximately 315,159 km, and a combined population of just under 70 million. Two sovereign states are located on the islands: Ireland (which covers roughly five-sixths of the island with the same name) and the United Kingdom of Great Britain and Northern Ireland. The British Isles also include three Crown Dependencies: the Isle of Man and, by tradition, the Bailiwick of Jersey and the Bailiwick of Guernsey in the Channel Islands, although the latter are not physically a part of the archipelago., Ben Nevis is the highest mountain in the British Isles, located in Scotland. Standing at above sea level, it is located at the western end of the Grampian Mountains in the Lochaber area of the Scottish Highlands, close to the town of Fort William., Scotland (Scots: ) is a country that is part of the United Kingdom and covers the northern third of the island of Great Britain. It shares a border with England to the south, and is otherwise surrounded by the Atlantic Ocean, with the North Sea to the east and the North Channel and Irish Sea to the south-west. In addition to the mainland, the country is made up of more than 790 islands, including the Northern Isles and the Hebrides., In topography, prominence characterizes the height of a mountain or hill's summit by the vertical distance between it and the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. A peak's "key col" is a unique point on this contour line and the parent peak is some higher mountain, selected according to various objective criteria. , The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World"., A country is a region that is identified as a distinct national entity in political geography. A country may be an independent sovereign state or one that is occupied by another state, as a non-sovereign or formerly sovereign political division, or a geographic region associated with sets of previously independent or differently associated people with distinct political characteristics. Regardless of the physical geography, in the modern internationally accepted legal definition as defined by the League of Nations in 1937 and reaffirmed by the United Nations in 1945, a resident of a country is subject to the independent exercise of legal jurisdiction., Subject: stuchd an lochain, Relation: instance_of, Options: (A) 1937 (B) addition (C) archipelago (D) bailiwick (E) border (F) chain (G) chain of islands (H) channel (I) coast (J) country (K) energy (L) england (M) geographic region (N) geography (O) group (P) history (Q) island (R) jurisdiction (S) league (T) line (U) marginal sea (V) may (W) metric (X) mountain (Y) munro (Z) occupation ([) ocean (\) oil (]) point (^) population (_) role (`) scottish (a) sea (b) share (c) six (d) state (e) surface (f) three (g) tradition (h) union (i) water
