Popularity Over Time
Noxious is an adjective that means harmful or unpleasant. It could describe a substance, or even a person. It’s often used in the definition of mephitic, which is an adjective commonly applied to gaseous odors. It’s all about the shades of meaning. That annoying person in your office who always takes credit for your work could be described as noxious, but if she also wears way too much perfume, she’s mephitic.

Mephitic is most often used in relation to a gas, or the air. Certain common chemicals in your house can turn dangerous when used inappropriately. Be careful not to mix bleach and ammonia, or you’ll create a gas that satisfies both definitions of mephitic — foul smelling and poisonous.
