|Underlining is used to indicate some form of stress or emphasis, either
by increased loudness or higher pitch. The more underlining, the greater
the emphasis. Therefore, underlining sometimes is placed under the first
letter or two of a word, rather than under the letters which are actually
raised pitch or volume. Especially loud talk may be indicated by upper case;
again the louder, the more letters in upper case. And in extreme case, upper
case may be underlined.
