Image syntagmata

In re-reading "Time of the object" I came up on this word, syntagma, in a Derrida quote. From dictionary.com:
"syn·tag·ma [sin-tag-muh], noun, plural syntagmas, syntagmata

1.	a syntactic unit or a word or phrase forming a syntactic unit
2.	a systematic collection of statements or propositions
[C17: from Late Latin, from Greek, from suntassein  to put in order; see syntax ]" Since the plural is syntagmata, reminding me of the syntagma "image schemata," I'm wondering... image syntagmata? Since it can be argued that image schemata are the base for syntax? Syntax...is that like the tax on cigarettes or alcohol???
