Etymology: Bromine, the element at the root of this term, is named after its smell. The name comes from the Greek "brômos," meaning "stench," a fitting label for a dark red liquid with a sharp, unpleasant odour. Chemists then built a family of technical verbs on that name. "Brominate" means to introduce bromine into a compound, usually by replacing one or more hydrogen atoms, and the "-ate" ending is the standard chemical suffix for verbs of that kind. The prefix "di-" comes from the Greek "dis," meaning "twice" or "two," and is used in chemistry to mean two of something. "Dibrominate" therefore describes adding two bromine atoms to a molecule. The "-ing" ending turns it into a present participle, which is why it works as a verb in progressive forms and as an adjective, as in "dibrominating agent." It is a purely technical coinage, built from familiar Greek parts and chemical suffixes.
