This new and more complicated patterning presents general grammar with a necessary choice: either to pursue its analysis at a lower level than nominal unity, and to bring into prominence, before signification, the insignificant elements of which it is constructed, or to reduce that nominal unity by means of a regressive process, to recognize its existence within more restricted units, and to find its efficacity as representation below the level of whole words, in particles, in syllables, and even in single letters themselves.
