In general, these contractions are used as parts of words wherever the letters they represent occur. Thus, the sign for and is used in hand, sandy, and Andrew; the sign for for is used in forge and forum; the sign for of is used in off, office, and roof; the sign for the is used in then, Thelma, and theory; and the sign for with is used in withhold and withe. Note that the use of these signs does not depend on pronunciation; whether the vowel is short or long, whether the consonant is hard or soft, or—in the case of the sign for of—whether the o is part of a double vowel, as in roof. Example:
Ethel and Sandy fell off the platform.
