Etymology: "Protectant" is a plain formation: the verb "protect" with the suffix "-ant" added. That suffix ultimately descends from the Latin present participle ending "-ans" (genitive "-antis"), which turned verbs into adjectives and nouns denoting someone or something doing the action. The "-ant" ending arrived in English through Old French, and its ancestry reaches back through Proto-Germanic and Proto-Indo-European, but in practice the story is one of straightforward affixation rather than a dramatic shift. The verb "protect" itself is borrowed from Latin "protegere," meaning "to cover in front," built from "pro-" (forward) and "tegere" (to cover). So the word's literal sense is something that covers in front of a thing. The modern meaning, a substance applied to guard surfaces against damage or decay, follows that picture closely: a coating stands between the material and whatever would harm it.
