taxemen.

1933 L. Bloomfield Lang. x. 166 A simple feature of grammatical arrangement is a grammatical feature or taxeme. A taxeme is in grammar what a phoneme is in the lexicon—namely, the smallest unit of form.

1943 K. L. Pike in Language XIX. 69 Somewhat diffidently I suggest the following classifications and relabelings as perhaps being a bit easier to handle than Bloomfield's... Tagmeme, a composite view of the basic composite taxemes of a linguistic form, at any one specific layer of structure. E.g. the total arrangement features of the form duchess considered as a single entity.

1967 M. Schlauch Language vi. 127 A taxeme, taken by itself, may have no meaning; when one or more taken together do have meaning the combination is called a tagmeme (for instance, duch + ess).

1970 G. C. Lepschy Survey Struct. Ling. v. 89 Taxemes occur in conventional grammatical arrangements.

1950 Webster's New Internat. Dict. Eng. Lang. Add. Taxemic.

1947 C. F. Hockett in Language XXIII. 274 This term [sc. tactics] seems simpler than ‘taxemics’ or ‘tagmemics’, which one might derive more directly from Bloomfield's labels.

1967 M. Schlauch Language vi. 128 It would seem that the terminology of taxemics requires further study.
