People currently use roughly 7,500 languages, finds study
WASHINGTON: Globally, people currently use roughly 7,500 languages, with English, Mandarin Chinese, Hindi, Spanish, Arabic and French the most common, counting native and non-native speakers. That is a lot of languages. But it is a far cry from the peak number historically.Researchers used mathematical modelling and insights from anthropology, linguistics and demography to estimate the number of languages used globally dating back about 12,000 years to around the end of the last Ice Age, covering a chapter in time called the Holocene epoch. They identified a period spanning the first millennium BC and first millennium AD when humankind may have spoken tens of thousands of different languages.The researchers also charted a major decline since this linguistic “golden age,” due to language replacement driven by factors such as the expansion of large empires in antiquity and European colonialism in the past several centuries. “Languages are meaningful to their communities. They carry knowledge, associations and memories,” said Claire Bowern, a professor of linguistics and anthropology at Yale University in Connecticut, and a leader of the study published in the journal Science. Many language families arose and evolved, with written language eventually emerging, first in Mesopotamia – Sumerian written in cuneiform script – during the fourth millennium BC, and separately in places like Egypt, China and Mesoamerica. The researchers estimated that the number topped out in a range from 30,000 to potentially more than 75,000 different languages used worldwide at any one time.The researchers used some ingenuity in reaching their estimates. “There’s no direct evidence for language numbers until very recently. We cannot rely on the extremely patchy records from antiquity. But because we know a lot about the relationships between languages and societies, we can use a couple of assumptions to make a simulation model of language diversification through time,” Bowern said.The researchers used data spanning 171 extant hunter-gatherer societies in Africa, South America and Southeast Asia to assess the size of ethno-linguistic groups near the beginning of the Holocene. They applied that to estimates of the human population at the time. People were dispersed in small bands around the world, living as nomadic hunter-gatherers. The researchers estimated that these scattered populations some 12,000 years ago spoke perhaps 4,500 to 6,200 languages.Bowern described some ways languages disappear. “The people who speak that language are killed or the people who speak that language shift or are forced to shift to another language,” Bowern said. About half of languages used today are deemed endangered. Bowern said that “90% of the world’s population speaks 10% of the world’s languages, so there are many languages with small numbers of speakers.”(BY REUTERS)
