romanticist n.

1650s, "of the nature of a literary romance, partaking of the heroic or marvelous," from French romantique "pertaining to romance," from romant "a romance," an oblique case or variant of Old French romanz "verse narrative" (see romance (n.)).

Of places, "characterized by poetic or inspiring scenery," by 1705. As a literary style, opposed to classical (q.v.) since before 1812; it was used of schools of poetry in Germany (late 18c.) and later France. In music, "characterized by expression of feeling more than formal methods of composition," from 1885. Meaning "characteristic of an ideal love affair" (such as usually formed the subject of literary romances) is from 1660s. Meaning "having a love affair as a theme" is from 1960. Related: Romantical (1670s); romantically; romanticality. Compare romanticism.

word-forming element meaning "one who does or makes," also used to indicate adherence to a certain doctrine or custom, from French -iste and directly from Latin -ista (source also of Spanish, Portuguese, Italian -ista), from Greek agent-noun ending -istes, which is from -is-, ending of the stem of verbs in -izein, + agential suffix -tes.

Variant -ister (as in chorister, barrister) is from Old French -istre, on false analogy of ministre. Variant -ista is from Spanish, popularized in American English 1970s by names of Latin-American revolutionary movements.
