6.9 Retaining Usual Braille Form of Base Word [X.34.b(1)]

Still another general rule restricting the use of contractions is that a contraction is not used if it would result in an alteration of the usual braille form of a base word. Thus, because the usual braille form of the word blemish does not contain the contraction for ble, this contraction must not be used when a prefix is added to it, as in unblemished. Similarly, the word ingenuous does not use the sign for ing, nor does the word disingenuous; the word blend does not contain the sign for ble, nor should the word pitchblende. In such words, the contractions are not used whether the word is written on one braille line or whether it is divided between lines. Examples:
