Despite critical disapproval, disinterested has come to be widely used by many educated writers to mean .uninterested. or .having lost interest,.as inSince she discovered skiing, she is disinterested in her schoolwork (a sense it had at an earlier stage of English, but which had in the interim become outmoded).Many maintain that the word can legitimately be used only in its sense of .having no stake in (an outcome or issue),.as inSince the judge stands to profit from the sale of the company, she cannot be considered a disinterested party in the dispute.
