What does constituent mean?
Constituent has two closely related core meanings. Most familiarly, it names a voter or resident whom an elected official represents — senators and representatives speak of 'their constituents' when describing the people whose interests they serve in government. More broadly and technically, a constituent is any essential part of which something larger is made: chemists speak of the constituents of a compound, linguists analyze sentences into their grammatical constituents, and engineers list the constituents of an alloy. The word also functions as an adjective meaning 'forming part of a whole', as in 'a constituent element'. Derived from the Latin constituere, 'to set up or establish', it shares roots with constitute and constitution. Its connotations are formal and precise, making it standard vocabulary in politics, science, law, and academic writing alike.
A voter or resident whom an elected official represents; alternatively, an essential component or element of a larger whole.
"Her proposal was popular among constituents in rural districts, but drew criticism from urban voters."
Serving to form or make up something larger; having the power to frame or establish, as in 'a constituent assembly'.
"Hydrogen is a constituent element of water, and of nearly every organic compound known to chemistry."
Almost always used attributively, directly before the noun it modifies.
Standard plural, used both for represented voters and for components of a mixture or system.
"The alloy's main constituents are copper and tin."
The word 'constituent' literally means someone who helps 'set up' — every election day, millions of voters perform the word's original Latin meaning without ever knowing it.

Etymology of constituent
Constituent comes from the Latin constituens, the present participle of constituere, meaning 'to set up, establish, or constitute' — formed from com- ('together') and statuere ('to place, set'). The word entered English in the late Middle English period via French, initially carrying the sense of something that serves as a component of a whole. Its political application to persons represented by an officeholder developed later, drawing on the idea of citizens as the parts that collectively 'establish' governing authority. It is a direct cognate of constitute, constitution, and constitutive, all from the same Latin root.

The adjective form is almost always attributive ('a constituent element', 'a constituent assembly') rather than predicative. The political sense carries a neutral-to-formal register.
