Where does constituent collide?

In the grammar of sentences, a constituent is a word or group of words that behaves as a single unit within the hierarchical structure of a sentence, so that it can be moved, replaced by a single pronoun, or stand alone as an answer to a question. Wells's 1947 Immediate Constituents set out a systematic method for cutting a sentence into its nested parts, and the tests he formalised remain the basis of how linguists identify these units. The referent is an abstract structural grouping inside a sentence, identified by grammatical behaviour, not a voter in a district, a component of a chemical mixture, or the collective power to found a constitution.[1]

In constitutional theory, the constituent power (from the French pouvoir constituant) is the extraordinary power of a people to create or refound the constitutional order itself, as distinct from the ordinary constituted powers that a finished constitution then establishes. Kalyvas's 2005 Popular Sovereignty, Democracy, and the Constituent Power traced this idea and its tension with everyday democratic institutions. Here the word names a collective founding authority, not an individual voter; it is unrelated to a grammatical unit in a sentence or a component of a chemical mixture, and it differs even from the political meaning, where a constituent is a single represented person rather than a people acting as founder.[2]
