Lojban - a logical language (introductory essay)
Constructed languages create words in two main ways. There are some, mainly fictional languages like Elvish or Klingon, which make up all the words from scratch. Most international languages, however, take their vocabulary from existing languages (in practice, European languages) and sometimes modify them to suit the spelling and grammar of the new language - Esperanto is a good example. Lojban falls half way between the two.
The root words (gismu in Lojban) were created by a computer from words in the six most widely-spoken languages in the world: Chinese, Hindi/Urdu, English, Spanish, Arabic and Russian. This is one of the advantages of Lojban - it doesn't give a privileged position to European languages. These are also languages that have had a lot of words in common other languages; for example, French and Italian share a lot of words with Spanish, and although Turkish is not on the list, I found in Lojban a lot of elements of Turkish which had come in from Arabic and Persian (which is quite close to Urdu). And of course English words like "television" and "taxi" have spread all over the world.
