Etymology: "Cinnamic" is a plain piece of chemical vocabulary: it is cinnamon with the adjective-forming ending "-ic" attached. The ending traces back through Latin "-icus", which was used to make adjectives meaning "of or relating to" a noun, and it reached English in the same family of forms that gave us words like "chemic" and "arsenic" with its adjectival sense intact. The base word, "cinnamon," came into English from Old French and ultimately from Greek and Semitic sources, so the ending is the only element here that English itself handled as a suffix. In practice "cinnamic" is used in chemistry, where it names a family of compounds derived from cinnamon oil or the cinnamic acid found in it, rather than in everyday speech.
