Note 111 — VI Types of Linguistic Structure
Reading edition
Footnote 111: We may assume that in these languages and in those of type D all or most of the relational concepts are expressed in “mixed” form, that such a concept as that of subjectivity, for instance, cannot be expressed without simultaneously involving number or gender or that an active verb form must be possessed of a definite tense. Hence group III will be understood to include, or rather absorb, group IV. Theoretically, of course, certain relational concepts may be expressed pure, others mixed, but in practice it will not be found easy to make the distinction.
