Abuse is a general term for the use or treatment of something (person, thing, idea, etc.) that causes some kind of harm (to the abused person or thing, to the abusers themselves, or to someone else) or is unlawful or wrongful. Its close synonyms are mistreatment and maltreatment. The word "misuse" has a more distant meaning of incorrect, uneducated use, not necessarily harmful to a person.
Abuse can be something as simple as damaging a piece of equipment through using it the wrong way, or as serious as severe maltreatment of a person. Abuse may be direct and overt, or it may be disguised and covert.
Several types of abuse include
-Spiritual abuse: abusive or aberrational practices identified in the behavior and teachings of some churches, spiritual and religious organizations and groups.
-Sexual abuse: The improper use of another person for sexual purposes, generally without their consent or under physical or psychological pressure (which may include children whether abused by parents, those in loco parentis or strangers).
-Physical abuse: Where one person inflicts physical violence or pain on another.
Verbal abuse: Verbal abuse (n.) when a person uses profanity or says things that threaten or make a person feel scared. (p. part of speech from Latin word abus meaning pain)
-Emotional abuse or psychological abuse: coercion, humiliation, intimidation, relational aggression, parental alienation or covert incest: Where one person uses emotional or psychological coercion to compel another to do something they do not want, or is not in their best interests; or when one person manipulates another's emotional or psychological state for their own ends (see battered person syndrome), or commits psychological aggression using ostensibly non-violent methods to inflict mental or emotional violence or pain on another.
-Drug abuse: the misuse of drugs, alcohol or other substances, usually a form of addiction. Law enforcement officials, among others, often define drug abuse as "any" use of illegal drugs, whether or not use is actually harmful to the user or to anyone else.
-Child abuse: Abuse, usually physical, emotional or sexual, directed at a child.
-Incest: Sexual activity between close family members.
-Spousal abuse (or domestic violence): Abuse, usually physical, or psychological abuse, directed at one's spouse.
-Elder abuse: Abuse, most often physical or in the form of psychological threats, directed at the elderly, especially in nursing homes and similar institutions.
-Human rights abuse: Violation of human rights.
-Verbal abuse: The use of foul language, obscenities or demeaning talk directed at another.
-Animal abuse: Abuse or cruelty directed at animals.
-Legal abuse: Vexatious litigation or malicious prosecution to retaliate, coerce, or emotionally/financially harm a person.
Abuse is not something you can just ignore.
