harmful
/ˈhɑːmfl̩/
Describes something that causes damage, injury, or negative effects. It is a broad term that covers both physical trauma and abstract deterioration, such as psychological or social harm. Unlike "toxic" or "lethal," which imply chemical danger or death, "harmful" is more general. It focuses on the result of an action or substance rather than the mechanism of destruction. It often carries a cautionary or judgmental tone. In formal contexts (medical, legal, or environmental), it serves as a factual descriptor of risk. In casual conversation, it is frequently used to describe behaviors or habits that are detrimental to one's well-being.
