Etymology: The root of "halogeno" is the Greek "hals," meaning "salt," joined to the suffix "-gen," from the Greek "gignesthai," "to be born" or "to produce." Together they describe something that produces salts. The chemist Jöns Jacob Berzelius coined "halogen" for the group of elements, including chlorine, bromine, and iodine, that readily combine with metals to form salts. "Halogeno" is the Romance-language form of that English coinage, used in Italian, Spanish, and Portuguese as an adjective meaning containing or relating to a halogen. It keeps the same Greek parts, so a speaker of those languages can see the chemistry in the word itself, much as the English term reveals it.
