mid-14c., "chronicler writing in French," from Anglo-French romancour, Old French romanceour, from romanz (see romance (n.)). From 1660s as "one who writes extravagant fictions;" later, "one inclined to romantic imagination" (the main 19c. sense); modern use for "seducer, wooer having a romantic quality" appears to be a new formation c. 1967 from romance (v.).
[I]n general, as now used, the term classical includes the composers active in instrumental music from somewhere about 1700 to say 1830. Hence the list includes among the great names those of Bach, his sons, Haydn, Mozart, Beethoven, Clementi, Dussek, Pleyel, Cramer, etc. The next step beyond the term classical is "modern romantic," the composers of which school may be taken to include all the writers for pianoforte from about 1829 (when Mendelssohn published the first "Songs without Words") down to the present. The term romantic in this sense means strongly marked, extraordinary, intending to tell stories and the like. ["Music, Its Ideals and Methods," W.S.B. Mathews, 1897]
But already by 1880s it was acknowledged the term had a double sense: Music that had withstood the test of time, as well as music of a style contrasted to "romantic." Later (early 20c.) it was contrasted to jazz (in this sense more often with reference to the orchestras than to the music itself). Still later it stood in contrast to popular music generally (mid-20c.). Classical history is the history of ancient Greece and Rome; ancient history is the history of mankind from the earliest reliable records to the fall of Rome (476 C.E.). Related: Classically.
"liaison at a particular time, by prearrangement," 1885, gradually evolving from date (n.1) in its general sense of "appointment." The romantic sense is by 1890s. Meaning "person one has a date with" is by 1900. Date-rape is attested by 1973.
