Although these contractions consist of single letters, they stand for whole words. Therefore, when such words appear in print in full capitals, in braille the double capital sign must precede the contraction. However, the words A, I, and O require only the single capital sign, for although they are words, they consist of only one letter. Example:
O, SAY CAN YOU SEE?
