Eclectic comes from the Greek adjective eklektikos, meaning “picking out, selecting what appears to be best,” which in turn comes from the verb eklegein, meaning “to select.” Eclectic was originally applied to ancient philosophers who were not committed to any single system of philosophy but instead selected whichever doctrines pleased them from every school of thought. Later, the word’s use broadened to cover other selective natures, as well as the use of elements drawn from different sources. For instance, a museum with an eclectic collection may showcase pieces from a variety of styles and periods and in different media. Similarly, a person may be said to have eclectic tastes if they enjoy a broad range, rather than a single genre, of film, music, literature, etc.
