Teruene (Terwene) is an IAL (International Auxiliary Language) based in part on Esperanto grammar (with Chinese influence), but with words which originate mainly from the world's five most spoken languages: Chinese (Mandarin), English, Spanish, Hindi and Arabic. (Some lists include French before Arabic, but French is sufficiently related to Spanish and English so it doesn't make sense to include it as a major source).
Spanish, English and Hindi represent the three most spoken branches of the Indo-European language family, which itself is spoken natively by about 45% of people worldwide. Chinese is by far the most spoken language in the Sino-Tibetan language family, which is spoken by about 22% of people. Finally, Arabic is the most spoken of the Afroasiatic languages, which in turn are spoken by 6% of the population. Arabic has also had a great influence over other languages, including Swahili and other Bantu languages.
It is an a posteriori agglutinative SVO language, although much more inclined to isolating languages than most agglutinative languages, including Esperanto.
