perfected or made shiny and smooth; "his polished prose"; "in a freshly ironed dress and polished shoes"; "freshly polished silver"
showing a high degree of refinement and the assurance that comes from wide social experience; "his polished manner"; "maintained an urbane tone in his letters"
abounding in or given to pompous or aphoristic moralizing; "too often the significant episode deteriorates into sententious conversation"- Kathleen Barnes
