Fun Fact
“Noxious” comes from the Latin noxa, meaning “harm” or “injury.” Historically, it was used to describe deadly gases, polluted air, and poisonous plants. In literature, Shakespeare frequently referenced noxious substances, such as the poison that killed Hamlet’s father. Beyond physical dangers, the word has taken on a figurative meaning, applying to toxic relationships, manipulative people, and harmful ideologies—reminding us that not all poisons come in a bottle.
(adjective) Distant from the ordinary; elevated, refined, or thin (as in air at high altitudes).
The scientist’s rarefied theories fascinated her peers but left the public scratching their heads.
From Latin rarefacere, meaning “to make thin.”
