[...] linguistic form may and should be studied as types of patterning, apart from the associated functions.
- Sapir (1921), a pag.60

This feeling for form as such, freely expanding along predetermined lines and greatly inhibited in certain directions by the lack of controlling types of patterning, should be more clearly understood than it seems to be.
- Sapir (1921), a pag.61

[...] every language has an inner phonetic system of definite pattern. [...] it has also a definite feeling for patterning on the level of grammatical formation.
- Sapir (1921), a pag.61

In defining the type [...] one must be careful not to be misled by structural features which are mere survivals of an older stage, which have no productive life and do not enter into the unconscious patterning of the language.
