Etymology

The word "treat" originates from the Old French "traitier" (to handle, negotiate), which itself comes from the Latin "tractare" (to manage, handle), a frequentative form of "trahere" (to pull, draw). The suffix "-ed" marks the past tense or past participle in English. Over time, "treat" evolved to encompass meanings like medical care (from the idea of "handling" an illness) and processing materials (from the idea of "manipulating" substances).
