What establishes its inherence in the body is the fact that linguistic deficiencies cannot be reduced to a unity, and that the primary disturbances affect sometimes the body of the word, the material instrument of verbal expression sometimes the word's physiognomy, the verbal intention, the kind of group image on the basis of which we succeed in saying or writing down a word exactly sometimes the immediate meaning of the word, what German writers call the verbal concept and sometimes the structure of the whole experience, not merely the linguistic experience, as in the case of amnesic aphasia examined above.
