Adverse is sometimes confused with averse, though the meanings are somewhat different. Adverse most often refers to things, denoting something that is in opposition to someone's interests — something one might refer to as an adversity or adversary — (adverse winds; an attitude adverse to our ideals). Averse usually refers to people, and implies one has a distaste, disinclination, or aversion toward something (a leader averse to war; an investor averse to risk taking). Averse is most often used with "to" in a construction like "I am averse to…". Adverse shows up less often in this type of construction, describing a person instead of a thing, and should carry a meaning of "actively opposed to" rather that "has an aversion to".
