Japanese language

Japanese (日本語, Nihongo, [nihõŋɡo] or [nihõŋŋo]) is an East Asian language spoken by about 125 million speakers, primarily in Japan, where it is the national language. It is a member of the Japonic (or Japanese-Ryukyuan) language family, whose relation to other language groups, particularly to Korean and the suggested Altaic language family, is debated.

Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century recorded a few Japanese words, but substantial texts did not appear until the 8th century. During the Heian period (794–1185), Chinese had considerable influence on the vocabulary and phonology of Old Japanese. Late Middle Japanese (1185–1600) saw changes in features that brought it closer to the modern language, as well as the first appearance of European loanwords. The standard dialect moved from the Kansai region to the Edo (modern Tokyo) region in the Early Modern Japanese period (early 17th century–mid-19th century). Following the end in 1853 of Japan's self-imposed isolation, the flow of loanwords from European languages increased significantly. English loanwords in particular have become frequent, and Japanese words from English roots have proliferated.

Language proficiency

Language proficiency or linguistic proficiency is the ability of an individual to speak or perform in an acquired language. As theories among pedagogues as to what constitutes proficiency go, there is little consistency as to how different organizations classify it. Additionally, fluency and language competence are generally recognized as being related, but separate controversial subjects. In predominant frameworks in the United States, proficient speakers demonstrate both accuracy and fluency, and use a variety of discourse strategies. Thus, native speakers of a language can be fluent without being considered proficient. Native-level fluency is estimated to be between 20,000–40,000 words, but basic conversational fluency might only require as little as 3,000 words.

Organizations

ACTFL

The American Council on the Teaching of Foreign Languages (ACTFL) distinguishes between proficiency and performance. In part, ACTFL's definition of proficiency is derived from mandates issued by the US government, declaring that a limited English proficient student is one who comes from a non-English background and "who has sufficient difficulty speaking, reading, writing, or understanding the English language and whose difficulties may deny such an individual the opportunity to learn successfully in classrooms where the language of instruction is English or to participate fully in our society."
