Synonyms: abuse, misuse, mistreat, ill-treat, maltreat
These verbs mean to treat wrongfully or harmfully. Abuse applies to injurious or improper treatment: "We abuse land because we regard it as a commodity belonging to us" (Aldo Leopold).
Misuse stresses incorrect or unknowledgeable handling: "How often misused words generate misleading thoughts" (Herbert Spencer).
Mistreat, ill-treat, and maltreat all share the sense of inflicting injury, often intentionally: "I had seen many more patients die from being mistreated for consumption than from consumption itself" (Earl of Lytton). "Experienced people ... become suspicious of those who by their own account are invariably ill-treated by the world" (Bertrand Russell). "[The professor was charged with] underpaying, neglecting, or otherwise maltreating his assistants" (David Rains Wallace).
