some superior or extraordinary quality ;
marked, famous. Syn. : eminent, illustrious, conspicuous, prominent.
Ant. : common, commonplace, obscure, ordinary.
Syn. dis. : Distinguished directly relates to persons and to deeds, and to persons for the sake of their deeds : it conveys the idea of social eminence or prominence as the result of public services rendered, or merit publicly exhibited. Eminent is only employed of persons — those who stand above their fellows: when things stand out conspicuously they are called prominent; e.g., the eminent characters of history, and the prominent events. Illustrious is used strictly only of persons, inasmuch as human acts or character can alone make things illustrious, as being the agents or recipients of what is illustrious ; thus we speak of illustrious heroes, nobles, titles. If we speak of illustrious deeds or events, it is as being done or brought about by human agency. Docile, adj. (do'-sîl or dos'-11), easily instructed
