Did You Know?

You are probably more familiar with the adjective innocuous, meaning "harmless," than with its antonymous relative "nocuous." Both "nocuous" and "innocuous" have immediate Latin predecessors: nocuus and "innocuus." (The latter combines "nocuus" with the negative prefix in-.) Both words can also be traced back to the Latin verb nocēre, meaning "to harm." Other "nocēre" descendants in English include "innocent" and "nocent," which means "harmful." "Nuisance" (which originally meant, and still can mean, "a harm or injury") is a more distant relative. "Nocuous" is one of the less common "nocēre" descendants, but it does turn up occasionally.
