The Nyaw language is a dialect of the Issan or Lao language with a few vocabulary, tonal and pronunciation differences. Speakers of the Nyaw language can be found mostly in the northeast portion of Thailand, and central Laos. In Thailand this language group is increesingly becoming integrated into the mainstream Issan language. It is a good likelihood that in 25 years very few true Nyaw speakers will remain. This is due to an aggressive campaign by the Thai government to modernize all Thai people, as well as due to outside influences of television, Internet and local radio broadcasts. Most younger members of northeastern tribal groups in Thailand prefer to be called Thai's rather than by their traditional tribal group.
The Spanish language (Castellano or EspaƱol) is a Romance language, the third or fourth most spoken language on the planet, spoken by about 352 million persons in 1999 in the seven continents, especially in The Americas (417,000,000 including second language users).
The language was brought to the Americas and Philippines, by the Spanish colonization since 16th century.
Spanish is one of the official languages of the African Union, the European Union and the United Nations.
