Definition: marked by expressions of love or affection; conducive to or suitable for lovemaking; a person of romantic temperament or disposition (noun)
We associate this word with sweetness and love, but it emerged from the conquering powers of the Roman Empire. The expansion of ancient Rome created various dialects of Latin called "romans." (These evolved into Italian, French, Spanish, and others - the Romance languages.) "Romans" were used to write popular stories involving chivalric or courtly love, and such tales became known as romances. If we describe Rome today as a "romantic" city, we're using a word that has travelled a long way to come home.
He supposed that they were engaged, or about to become engaged, but instead of being in the least romantic or exciting, that was as dull as everything else; it annoyed him, too, to think that they were in love.
— Virginia Woolf, The Voyage Out, 1915
