The utterances of a language are examined. Recurrent partials with constant meaning ("ran away" in "John ran away" and "Bill ran away") are discovered; recurrent partials not composed of smaller ones ("-way") are "alternants" or "morphs". [...] By definition, a morph has the same phonemic shape in all its occurrences. Because we operate with whole utterances, morphs are not always composed of continuous uninterrupted stretches of phonemes, but they are always composed of phonemes.
