  1. poisonous

    Pernicious (Latin per, through, and neco, kill) signifies having the power of destroying or injuring, tending to hurt or kill. Pernicious is stronger than injurious; that which is injurious is capable of doing harm; that which is pernicious is likely to be destructive. Noxious (Latin noceo, hurt) is a stronger word than noisome, as referring to that which is injurious or destructive. Noisome now always denotes that which is extremely disagreeable or disgusting, especially to the sense of smell; as, the noisome stench proclaimed the presence of noxious gases.

How to use poisonous in a sentence?

  1. Lindsay Tarasco:

    I smelled something, so I took a deep breath in. Bad mistake, i realized there was definitely something poisonous in the air.

  2. Frederick Saunders:

    Pride, like laudanun and other poisonous medicines, is beneficial in small, though injurious in large quantities. No man who is not pleased with himself, even in a personal sense, can please others.

  3. British Prime Minister David Cameron:

    For all our successes as a multiracial, multifaith democracy, we have to confront a tragic truth that there are people born and raised in this country who don't really identify with Britain -- and feel little or no attachment to other people here, so when groups like ISIL seek to rally our young people to their poisonous cause, it can offer them a sense of belonging that they lack here at home.

  4. David Cameron:

    All of us have been horrified by the way that British teenagers appear to have been radicalised and duped by this poisonous ideology of Islamist extremism while at home on the internet in their bedrooms, given reports that one of the girls was following as many as 70 extremists online, this case underlines the importance of the work we are doing with social media companies.

  5. United States:

    When you listen to the kind of poisonous rhetoric that's coming from the other side it's a race to the bottom on who can say the nastiest, ugliest things about immigrants with ignoring the reality that they came from somewhere, too, you know ? Marco Rubio's family fled a dangerous regime that wanted to get nuclear weapons, that were sworn enemies of the United States, where's Marco Rubio come from ? Cuba. But Marco Rubio and the Republicans turn Marco Rubio and the Republicans backs on any Syrians coming into this country. How is it any different ?
