97. Usually the word distinguished by vocalization need not be fully vocalized; that is to say, all the vowels need not be inserted. Generally a single characteristic or distinctive vowel (that is, a vowel belonging to one of the words and not the other) is sufficient. But a rare word, if introduced into a phrase, should be vocalized as fully as time may allow, just as it would be by any careful writer if it stood alone. It is fully vocalized, not for fear it may be mistaken for some other word, but for fear that, being a strange outline, it may not be read at all.

98. A word which sometimes needs vocalization may not need it in every case. The stenographer, as he grows in experience, will frequently see on the instant, as he writes a word, the impossibility of misreading the unvocal-ized outline, and will, of course, omit vocalization, though the same word in another case might require it.
