        DIACRITICALS USED IN THE TABLE



        The word diacritic comes from a Greek word meaning to 

        separate. It refers to the accent marks employed to separate,

        or distinguish, one form of pronunciation of a vowel or 

        consonant from another.



        This note is included to familiarize the user with the codes 

        used to represent diacriticals found in the table, and the 

        values usually associated with them. In the table, the code 

        for a diacritical is preceded by a backslash and is followed,

        without a space, by the letter it is modifying.



        This note is organized as follows: the code is listed first, 

        followed by the name of the accent mark, if applicable, a 

        brief description of the appearance of the diacritical and a 

        short narrative on its usage.



        acute accent; a straight diagonal line extending from upper 

        right to lower left. The acute accent is used in most 

        languages to lengthen a vowel; in some, such as Oscan, to 

        denote an open vowel.  The acute is also often used to 

        indicate the stressed syllable; in some transcriptions it 

        indicates a palatalized consonant.



        diaeresis or umlaut; two dots surmounting the letter. In 

        Romance languages and English, the diaeresis is used to 

        indicate that consecutive vowels do not form a dipthong (see 

        below); in modern German and Scandinavian languages, it 

        denotes palatalization of vowels.



        circumflex; a chevron or inverted 'v' shape, with the apex at

        the top. Used most often in modern languages to indicate 

        lengthening of a vowel.



        tilde; a curving or waving line above the letter. The tilde 

        is a form of circumflex. The tilde is used most often in 

        Spanish to form a palatalized n as in the word 'ano', 

        pronounced 'anyo'.  It is also used occasionally to indicate 

        nasalized vowels.



        macron; a straight line above the letter. The macron is used 

        almost universally to lengthen a vowel.



        breve; a concave semicircle or 'u' shape surmounting the 

        letter.  Originally used in Greek, the breve indicates a 

        short vowel.



        a small circle or 'o' above the letter. Frequently used in 

        Scandinavian languages to indicate a broad 'o'.



        e dipthong or ligature; transcribed as two letters in contact

        with each other. The dipthong is a combination of vowels that

        are pronounced together.



        cedilla; a curved line surmounted by a vertical line, placed 

        at the bottom of the letter. The cedilla is used in Spanish 

        and French to denote a dental, or soft, 'c'. In the new 

        Turkish transcription, 'c' cedilla has the value of English 

        'ch'.  In Semitic languages, the cedilla under a consonant 

        indicates that it is emphatic.



        check or inverted circumflex; a 'v' shape above the letter. 

        This accent is used widely in Slavic languages to indicate a 

        palatal articulation, like the consonant sounds in the 

        English words chapter and shoe and the 'zh' sound in 

        pleasure.



        a single dot above the letter. This diacritical denotes 

        various things; in Lithuanian, it indicates a close long 

        vowel. In Sanskrit, when used with 'n', it is a velar sound,
