mistreated

The word 'mistreated' is built upon the core verb 'treat', which entered English via Old French from the Latin tractare, meaning to handle or manage, itself a frequentative form of trahere (to pull, draw). The Germanic prefix 'mis-' was attached to verbs in Old English to signify an action done badly, wrongly, or amiss. Therefore, the literal construction "to handle badly" perfectly captures the modern abstract meaning of acting with cruelty or injustice towards a person or thing. The suffix '-ed' follows the standard pattern for forming the regular past tense and past participle in English, solidifying the word's grammatical function to describe a completed action of poor treatment.
