disinterested
UK: dɪsˈɪntrɪstɪd | US: dɪsˈɪntrəstɪd
adj. not influenced by personal advantage; impartial
adj. (archaic) having no interest or concern; indifferent
The word "disinterested" combines the prefix "dis-" (from Latin, meaning "not" or "opposite of") with "interest" (from Latin interesse, "to be of importance") and the suffix "-ed" (forming adjectives). Originally, it meant "unconcerned" or "indifferent," but its meaning shifted in the 17th century to emphasize impartiality—lacking bias or personal stake. This evolution reflects a linguistic focus on objectivity in decision-making, distinguishing it from "uninterested" (which retains the older sense of indifference).
