interesting

The word "interesting" is built upon the core concept of "interest," which originates from the Latin phrase inter esse, literally meaning "to be between." This evolved through Medieval Latin and Anglo-French to signify something that "makes a difference" or "concerns" someone, eventually settling on the modern sense of engaging one's attention or curiosity. The addition of the English adjectival suffix "-ing" transforms the noun/verb into a descriptor, literally meaning "having the quality of engaging attention." Thus, the modern abstract meaning of "attracting attention" is a direct semantic evolution from the ancient idea of something that "comes between" you and your indifference, compelling your notice.
