additive
UK: ˈæd.ɪ.tɪv | US: ˈæd.ə.t̬ɪv
n. a substance added to another to improve or preserve it
adj. relating to or produced by addition
The word "additive" originates from the Latin additivus, derived from addere ("to add," combining ad- "to" + dare "give"). The morpheme "add" preserves the core meaning of joining or combining, while "-itive" (via Latin -itivus) forms adjectives indicating a tendency or capacity. The term evolved in English (17th century) to describe both mathematical operations and material substances added to enhance properties.
