Passage 5
Questions 21 to 25 are based on thefollowing passage.
Constructed languages, alsoknown as artificial, planned or invented languages, are usually designed for aspecific purpose. There are several types of constructed languages, dependingon the use. People have created artificial languages to improve communicationbetween speakers, for creative purposes as in writing and films about fantasyworlds, to revive dead languages, and to talk to and instruct computers.
Constructed languages differfrom others because their entire structure, including grammar, vocabulary, andphonology (sound system) have been planned deliberately. Constructed languagescan be built by existing languages, or based on entirely new principles.
Constructed languages thatare created with entirely new elements, such as sound symbols or numbers, andthen given meanings, are known as " priori" languages. Examples of"a priori" languages are fictional languages like Sindarin or Elvish,created by JRR Tolkien, or the languages spoken in the TV series Game ofThrones directed by Alan Taylor and three others.
Because the purposes behindthe creation of constructed languages are so varied, they are very differentfrom each other. Here are some familiar examples of constructec languages.
