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.

   Synonyms:
   bad, baneful, deadly, deleterious, destructive, detrimental, evil, foul, harmful, hurtful, injurious, insalubrious, mischievous, noisome, noxious, pernicious, perverting, pestiferous, pestilential, ruinous, unhealthful, unwholesome
