3. Polysaccharide derivatives sourced from marine algae that function as gelling, thickening, and emulsifying agents in various industrial and pharmaceutical processes

Etymology: "Alginates" is the plural of "alginate," a noun for the salts and esters of alginic acid. Alginic acid is itself a polysaccharide extracted from brown seaweeds, and the chemical name comes from "algin," a coinage based on the Latin "alga," meaning seaweed. The suffix "-ate" was added to name the salts and esters formed from that acid. The suffix has a long lineage, descending through Latin "-atus" and Proto-Italic forms from older Indo-European roots, and English borrowed it as "-ate" to mark chemical salts. Because the suffix is a chemist's tool rather than a folk word, the whole term is a technical construction built from a plant-based root and a standard chemical ending.
