Etymology: Chemoreception is a plain modern compound, assembled in English from two parts. The first, "chemo-", comes from New Latin "chēmīa", a form of "chemistry" that descends from the Arabic "al-kīmiyāʔ", "the alchemy," which was borrowed from Medieval Latin "alchēmia." That chain runs back through the Greek "khumeíā," a word originally tied to metalworking and the mixing of substances, and it was that older sense of "alchemy" which gave the modern science its name. The second part, "reception," is an ordinary English word meaning the act of taking in something from outside, as in receiving a signal. Put together, the parts describe exactly what the term means: the reception of chemical stimuli. The compound records a surprisingly long road, since a word tied to ancient metal-working now names how a moth finds a mate or how a bacterium senses sugar. The "chemo-" element is also what links it to a family of other terms built the same way, such as "chemotaxis," in which an organism moves toward or away from a chemical.
