Algid is a rather cold and lonely word, etymologically speaking-it's the only word in any of the dictionaries we publish that comes from the Latin word algēre, meaning "to feel cold." Also, English speakers have warmed to its many synonyms-among them "cold," "frigid," "arctic," "chill"-much more readily than they've taken to "algid." Even its compatriot, "gelid"-also a Latin-derived adjective that can describe ice and arctic temperatures-has managed to outpace it in most decades of the approximately 400 years the words have been in use. In one context, though, "algid" does something its synonyms don't: it describes a severe form of malaria that is marked by prostration, cold and clammy skin, and low blood pressure-a meaning that probably hasn't done much to endear the more general use to speakers of English.
