Phonological rules may change the phonemes involved. In such cases, pipes (", ") or double slashes may be used in transcription to distinguish the underlying form from its phonemic realization. For example, the word "cats" has the phonemic representation . If it is assumed that the underlying form of the English plural suffix is a sound, the underlying form of "cats" would be .
