[OED:] 7. Freq. as Romantic. Designating, relating to, or characteristic of a movement or style during the late 18th and 19th centuries in Europe marked by an emphasis on feeling, individuality, and passion rather than classical form and order, and typically preferring grandeur, picturesqueness, or naturalness to finish and proportion. Generally opposed to classical (see classical adj. 7).
My following questions concern only the definition 7 above: 1. Precisely which (of the many etymons with the root 'roman') were the etymon(s) of 'Romanticism'?
2. How did the etymon(s) of 'Romanticism' shift semantically into defn. 7 above?
Per Wikipedia, 'the group of words with the root "Roman" in the various European languages, such as romance and Romanesque, has a complicated history.' So the excessive number of possible etymons precludes even conjecture: is it the Latin Romanicus, Vulgar Latin *romanice scribere, Old French romanz, etc?
