Etymology: Fumarate takes its name from the plant fumitory, whose Latin name, "Fumaria," gave rise to "fumaric acid," the acid first obtained from that plant. The word is therefore a chemical name built from a botanical one, and the plant itself was named for smoke: "fumus" is Latin for smoke, a reference to the smoky-smelling juices of the fumitory. The chain of word-building is simple. Chemists took "fumaric acid" and added the suffix "-ate," which in English chemistry marks a salt or ester of an acid. Acetate, nitrate and sulfate follow the same pattern, so "fumarate" is what you get when the acid's name is turned into the name of its salts and esters. The suffix itself has a long ancestry, descending from Latin "-atus," a participial ending that English borrowed in forms like "-ate" for adjectives and nouns. In chemistry it became a fixed label, so anyone seeing "-ate" in a name knows the compound is derived from an acid.
