"Gestes" (also "gests") derives from Old French "geste" (exploit, story), referring both to heroic deeds and to tales recounting them—the term encompassed both action and narrative. Medieval romance titles like "Gesta Romanorum" (Deeds of the Romans) employed it, establishing "geste" as the proper term for adventure narratives. Poets used it when referring to tales of chivalric adventure, knightly quests, and heroic exploits. The word's dual meaning—both deed and tale—reflected medieval understanding that great deeds demanded narration and achieved immortality through story. "Gestes" appeared in contexts of storytelling and reputation where fame depended on narrative preservation. Its archaic quality made it essential for romance and epic, genres celebrating heroic action. The term's association with oral tradition and minstrelsy connected written poetry to performance roots, emphasizing literature's role in preserving and celebrating deeds through narrative craft.

Gestes appears primarily in medieval romance titles and descriptions of heroic narrative: "gestes of Arthur," "romantic gestes." The term encompasses both the deeds themselves and narratives recounting them, showing medieval unity between act and telling. Related to "jest" (which evolved to mean joke, showing semantic drift) and "gesture." Essential for analyzing medieval narrative categories, the relationship between deed and story, and heroic literature's self-conception. The term appears in prologues and epic invocations where narrators announce their subject matter. Useful for discussing genre categories, how medieval literature classified itself, and the performative aspects of heroic narrative. The French origin reflects Romance language dominance in medieval literary terminology. Its obsolescence obscures the medieval genre system.
