[…] just as utterances can be represented by sequences of elements such that each element occurs in various utterances, so the morphemic elements, which represent segments of utterances, can be considered as sequences of smaller elements.
- Harris (1951), a pag.23

It is therefore possible to describe each morphemic element as a unique combination of sound elements. Breaking the morphemic elements down into these smaller parts does not help us in stating the interrelations among morphemes; we could deal just as well with whole unanalyzed morphemes. This further analysis of the morphemic elements merely enables us to identify each of them more simply, with a much smaller number of symbols (one symbol per phoneme, instead of one symbol per morpheme).
- Harris (1951), a pag.23

[…] identifying each morphemic element as a particular combination of the previously discovered phonemes is more convenient than determining afresh the phonetic uniqueness of each morphemic element.
- Harris (1951), a pag.23

In dictionaries, morphemic elements are defined as a correlation between morphemically segmented phonemic sequences and features of social situations (meanings).
