1 Like most languages, Koro is unwritten and transmitted orally.

2 That third language was Koro.

3 Moreover, linguists are not sure how Koro has survived this long as a viable language.

4 Koro brings an entirely different perspective, history, mythology, technology and grammar to what was known before.

5 Few words in Koro were the same as in Aka: mountain in Aka is "phu," but "nggo" in Koro; pig in Aka is "vo," but in Koro "lele."

6 They even believe that the perceived condition, called koro, can be deadly.

7 Listening, the researchers at first suspected Koro to be a dialect of Aka, but its words, syntax and sounds were entirely different.

8 Koro is not generally understood by western doctors, so if necessary he should seek shamanic help from a healer of his own culture.

9 "Koro could hardly sound more different from Aka," Harrison writes. "They sound as different as, say, English and Japanese."

10 The linguists made the first-ever recordings of Koro, capturing thousands of words during their expedition, which began in 2008.

11 On a scientist's tally sheet, Koro adds just one entry to the list of 6,909 languages worldwide.

12 Earlier, Zhang also met respectively with visiting Japanese Deputy Minister for Foreign Affairs Bessho Koro and State Secretary for Foreign Affairs Yutaka Banno.

13 "We found something that was making its exit, was on the way out," said National Geographic fellow Gregory Anderson, one of the leaders of the expedition that discovered Koro.

14 While recording the vocabularies, they detected a third language -- Koro.

15 By contrast, the Aka people number about 10,000 living in close relations with Koro speakers in a district of the state of Arunachal Pradesh, where at least 120 languages are spoken.

16 The team will return to India to continue studying Koro in November.

17 A team of linguists announced Tuesday that they have discovered a new and unique language, called Koro, in northeastern India(), but immediately warned that it was highly endangered.

18 While the number of spoken languages continues to decline, at least one new one has been added to the inventory, though Koro too is on the brink of extinction.

19 In the news release, the linguists described their discovery as bittersweet: Of the approximately 800 people who speak Koro, few are under the age of 20, meaning the language is endangered.

20 After further investigation, leaders of the research announced last week the discovery of a "hidden" language, known locally as Koro, completely new to the world outside these rural communities.
