1. harmful

   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, hurtful, injurious, insalubrious, mischievous, noisome, noxious, pernicious, perverting, pestiferous, pestilential, poisonous, ruinous, unhealthful, unwholesome

   Antonyms:
   advantageous, beneficent, beneficial, favorable, good, healthful, helpful, invigorating, life-giving, profitable, rejuvenating, salutary, serviceable, useful, wholesome
