1885 G. L. Goodale in A. Gray & G. L. Goodale Bot. Text-bk. (ed. 6) II. ii. vi. 213 Pfeffer applies a general term, Tagma, to all aggregates of molecules, thus bringing under one head the pleon, micella, and micellar aggregate; and he applies the name Syntagma to all bodies made up of tagmata.

1889 J. S. Burdon-Sanderson in Nature 26 Sept. 524 That an element of living material, is not equivalent to a molecule, however big or complex, but must rather be an arrangement or phalanx of molecules of different kinds. Hence the word tagma, first used by Pfeffer, has come to be accepted as best expressing the notion.

2. Zoology. Each of the morphologically distinct regions, comprising several adjoining segments, into which the bodies of arthropods and some other metamerically organized animals are divided. Chiefly plural.

1949 Archivum Linguisticum 1 1 Such distinctions as that of morpheme and ‘tagma’ as the constituents of the syntagm provide the necessary correction. But there is a different sense in which morpheme and tagma may share in the expression of the meaning of a syntagm: a feature of meaning may be distributed over both.

b. In tagmemics, the smallest meaningful unit of grammatical substance (contrasted with tagmeme).
