5. Almost every word has an accent, but very seldom has more than one; and, when this happens, it is an acute thrown back upon the last syllable from one of those words called enclitics (_leaning back_), which in that case has none, unless it be followed by another enclitic. In no other case than this can a last syllable have an acute accent, except before a full-point, colon, or note of interrogation, when the grave accent of the last syllable is changed to an acute,—a circumstance which has often led printers, who were ignorant of the reasons for accenting the same word differently in different situations, to think that there was an error in their copy, and thus to make one in their proof. Most errors, however, proceed from those who do not think at all about the matter. PLAN OF GREEK CASES. The following plan of cases for Greek type is probably more convenient than any other. A Roman case may readily be altered to accommodate the lower-case sorts. Compositors who aspire to a full knowledge of their art should by all means make themselves familiar with Greek and Hebrew letters and cases. [Illustration: GREEK UPPER CASE.] [Illustration: GREEK LOWER CASE.] HEBREW. The Hebrew alphabet has twenty-two letters. Column No. 1 of the following table indicates the force of Hebrew letters when read without points. Column No. 2 gives their force when the language is printed with the Masoretic points or vowels, which are of later date than the letters. The names and numerical value of the characters are also shown. THE HEBREW ALPHABET.
