Archipelago

An archipelago (ⁱ/ɑːrkᵻˈpɛləɡoʊ/ ark-i-PEL-ə-goh), sometimes called an island group or island chain, is a chain, cluster or collection of islands. The word archipelago is derived from the Greek ἄρχι- – arkhi- ("chief") and πέλαγος – pélagos ("sea") through the Italian arcipelago. In Italian, possibly following a tradition of antiquity, the Arcipelago (from medieval Greek *ἀρχιπέλαγος and Latin archipelagus) was the proper name for the Aegean Sea and, later, usage shifted to refer to the Aegean Islands (since the sea is remarkable for its large number of islands). It is now used to refer to any island group or, sometimes, to a sea containing a small number of scattered islands.

Types

Archipelagos may be found isolated in bodies of water or neighboring a large land mass. For example, Scotland has more than 700 islands surrounding its mainland which constitute an archipelago. Archipelagos are often volcanic, forming along island arcs generated by subduction zones or hotspots, but may also be the result of erosion, deposition, and land elevation. Depending on their geological origin, islands forming archipelagos can be referred to as oceanic islands, continental fragments, and continental islands. Oceanic islands are mainly of volcanic origin. Continental fragments correspond to land masses that have separated from a continental mass due to tectonic displacement. Finally, sets of islands formed close to the coast of a continent are considered continental archipelagos when they form part of the same continental shelf so islands are just exposed continental shelf.

Shut up

"Shut up" is a direct command with a meaning very similar to "be quiet"', but which is commonly perceived as a more forceful command to stop making noise or otherwise communicating, such as talking. The phrase is probably a shortened form of "shut up your mouth" or "shut your mouth up". Its use is generally considered rude and impolite.

Initial meaning and development

Before the twentieth century, the phrase "shut up" was rarely used as an imperative, and had a different meaning altogether. To say that someone was "shut up" meant that they were locked up, quarantined, or held prisoner. For example, several passages in the King James Version of the Bible instruct that if a priest determines that a person shows certain symptoms of illness, "then the priest shall shut up him that hath the plague of the scall seven days". This meaning was also used in the sense of closing something, such as a business, and it is also from this use that the longer phrase "shut up your mouth" likely originated.
