Unlike the later form of the novel and like the chansons de geste, the genre of romance dealt with traditional themes. These were distinguished from earlier epics by heavy use of marvelous events, the elements of love, and the frequent use of a web of interwoven stories, rather than a simple plot unfolding about a main character. The earliest forms were invariably in verse, but the 15th century saw many in prose, often retelling the old, rhymed versions.
The romantic form pursued the wish-fulfillment dream where the heroes and heroines were considered representations of the ideals of the age while the villains embodied the threat to their ascendancy. There is also a persistent archetype, which involved a hero's quest. This quest or journey served as the structure that held the narrative together. With regards to the structure, scholars recognize the similarity of the romance to folk tales. Vladimir Propp identified a basic form for this genre and it involved an order that began with initial situation, then followed by departure, complication, first move, second move, and resolution. This structure is also applicable to romance narratives.

Overwhelmingly, these were linked in some way, perhaps only in an opening frame story, with three thematic cycles of tales: these were assembled in imagination at a late date as the "Matter of Rome" (actually centered on the life and deeds of Alexander the Great conflated with the Trojan War), the "Matter of France" (Charlemagne and Roland, his principal paladin) and the "Matter of Britain" (the lives and deeds of King Arthur and the Knights of the Round Table, within which was incorporated the quest for the Holy Grail); medieval authors explicitly described these as comprising all romances.
In reality, a number of "non-cyclical" romances were written without any such connection; these include such romances as King Horn, Robert the Devil, Ipomadon, Emaré, Havelok the Dane,Roswall and Lillian, Le Bone Florence of Rome, and Amadas.
Indeed, some tales are found so often that scholars group them together as the "Constance cycle" or the "Crescentia cycle"—referring not to a continuity of character and setting, but to the recognizable plot.
