Abuse, Maltreatment, Mistreatment, Persecution 和 Wrong
Abuse: the most general term in this groupm, covers all injurious use or treatment by word or act. It does not always connote a deliberate act.
Maltreatment: is thus more general than maltreatment and need not imply physical abuse or even the desire to harm.
Mistreatment: however, suggests harsher or more consciously cruel treatment than mistreatment, which can apply to acts whose chief effect is psychological rather than physical.
Persecution: Punishment or harassement usually of a severe nature on the basis of race, religion, or political opinion in one’s country or origin.
Wrong: Treat with injustice.
五个单词均有"虐待"或"滥用"的含义。其中,abuse为最常用,可指所有诽谤中伤或有害言词或行为,不管是否是故意,常用于滥用特权、权力、法律程序、毒品以及虐待儿童、妇女等,如A policeman abusing his authority by searching the house without a warrant. maltreatment 和mistreatment十分近义,均指有卑劣动机的行为。相比之下,mistreatment的虐待程度较maltreatment轻,且其不一定具有身体上的虐待或故意伤害;而maltreatment则通常以精神上的虐待为主。persecution多指因种族、宗教或信仰等原因而施加的迫害或虐待。wrong主要指在无正当理由或原因的情况下受到不公正或有害的待遇,或自己的权利受到侵犯。
