A simple feature of grammatical arrangement is a grammatical feature or 'taxeme'.- Bloomfield (1935), a pag.166
A taxeme is in grammar what a phoneme is in the lexicon - namely, the smallest unit of form.- Bloomfield (1935), a pag.166
[...] a taxeme, taken by itself, in the abstract, is meaningless.- Bloomfield (1935), a pag.166
