Advanced and Retracted Tongue Root

Advanced And Retracted Tongue Root

In phonetics, advanced tongue root and retracted tongue root, abbreviated ATR or RTR, are contrasting states of the root of the tongue during the pronunciation of vowels in some languages, especially in West Africa, but also in Kazakh and Mongolian. It has in the past been suggested that this may also be the basis of the distinction of tense and lax vowels in European languages such as German, but this no longer seems tenable.

Famous quotes containing the words advanced, retracted, tongue and/or root:

    Predatory capitalism created a complex industrial system and an advanced technology; it permitted a considerable extension of democratic practice and fostered certain liberal values, but within limits that are now being pressed and must be overcome. It is not a fit system for the mid- twentieth century.
    Noam Chomsky (b. 1928)

    For it is wretchedness that endures, shedding its cancerous light on all it approaches:
    Words spoken in the heat of passion, that might have been retracted in good time,
    All good intentions, all that was arguable.
    John Ashbery (b. 1927)

    The eye of man hath not heard, the ear of man hath not seen, man’s hand is not able to taste, his tongue to conceive, nor his heart to report what my dream was!
    William Shakespeare (1564–1616)

    There is a certain class of unbelievers who sometimes ask me such questions as, if I think that I can live on vegetable food alone; and to strike at the root of the matter at once,—for the root is faith,—I am accustomed to answer such, that I can live on board nails. If they cannot understand that, they cannot understand much that I have to say.
    Henry David Thoreau (1817–1862)
